5S Screen Redraw/Refresh Issues iOS 8 & 8.0.2

Anyone experiencing partial/incomplete screen redraws, with bottom half of screen as just blank?
Since updating to iOS 8 and subsequently to iOS 8.0.2 on iPhone 5S, I been getting frequent incomplete screen refreshing/redrawing where I end up bottom 1/2 of screen is blank. Only occurs in normal (portrait) orientation. It occurs in both Apple apps and miscellaneous 3rd party apps. When using Mobile Safari, rotating phone orientation sometimes causes a refresh that will fill screen with missing 1/2 of page, sometimes it does NOT work and manually tapping URL refresh icon is required and sometimes more than once. As far other apps it is hit or miss as to encountering the incomplete screen draw and very random as to what will trigger an effective refresh to get the entire screen to redraw to completion - sometimes rotating phone orientation, sometimes backing out of screen or app all the way.
Upon experiencing this behavior after the iOS 8 upgrade, I did a hard reset of phone and set up as new, but the problem was still there. Upon upgrading to 8.0.2 and discovering the issue existed, soft reset and then hard reset phone to no avail either time.

Hi SeekerJ,
If you are still having persistent display issues after a hard reset, you may want to make sure you have a current backup of your data in iTunes, then try restoring your iPhone to factory settings and testing it in that default condition to see if the issues persist before restoring your data. You may find the following article helpful:
Use iTunes to restore your iOS device to factory settings

Performance Issues - Screen Redraw etc.?

I have a new MacBook Pro 15" (8GbRAM, 2 GHz i7) Using 30" Cinema Display, OS 10.7.2. I'm using Photoshop CS 5.1 (12.1 x64) Extended. After working for awhile I get performance lag -mostly drawing, cloning etc. Then the cursor starts behaving unpredictably -usually drawing slightly BELOW where the crosshairs are. Then the screen refreshes slows and the screen redraw occurs in very large blocks -VERY slowly. Reloading PShop doesn't help, but rebooting the laptop does solve the problem -until it happens again. In an earlier post I was advised that PShop CS4 was the cause (not compatible w/Lion). But I now have the latest version of Photoshop (my primary application).
- In this situation, I would suspect corrupted PShop Prefs, but I don't think that's the case, as reboot solves the problem. It was also the exact same issue when I ran CS4.
- Could this be an issue wuth using the 15" Macbook Pro with a 30" display? I was also advised that I could NOT upgrade the video card (soldered to motherboard) but this is not a MacBook Air.
- RAM issue? I did upgrade to 8Gb -but I purchased quality RAM from a reputable dealer. I have had no crashes or other issues (other than the Photoshop issue. I will test the RAM.
- Any know CS5 issues/bugs in this area?
Thanks

I think you're seeing more of the 1.7 video driver bugs. The cursor offset is a known one, along with some "cursor doesn't draw correctly" bugs.
You can try turning off OpenGL drawing in preferences to avoid many of the problems (don't know if that'll fix the cursor or not).
But the real fixes need to come from Apple fixing their display drivers.

Screen redraw issues after update to 10.7.4

Anyone else seeing screen redraw issues since updating to 10.7.4? Suddenly, the zoom tool stops working or causes visual errors.

thank you FFS48, it really helped and might work fine as temporary solution. I was about to restore my OS from backup to 10.7.3 version... as booting from it made no errors. The latest 10.7.4 update filled my log filles with different error messages like:
2012-05-10 23:53:17,000 kernel: SMC::smcReadKeyAction ERROR PC2C kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff8030d4f000

which might be caused by iStatMenus as these log entries are allways next to iStat log entries.
I often need to access my Mac Pro using Back to my Mac from my MBP. Do you know will it still be possible having WiFi on MacPro off?
It is strange, that the latest update delivered more visible problems than benefits....
What I tried to solve the problem and that did not work:
- Disable WiFi sync on iTunes (after reading some forums discussing similar problem)
- Uninstalled Xcode (as some forums suggested)
It is some how related to WiFi and iOS devices that sync to that computer. Switching these iOS devices off - removes the problem, and I believe it should be reported to Apple.
Is there any URL to Apple bug submit form?

Screen redraw issues

Hi everyone
My new Macbook appears to have screen redraw issues (as I've mentioned in other posts). It often does not redraw the screen quickly or smoothly. It may redraw the screen in bands from the top, or the Dock may come up in jerks. Also, the cursor often freezes, especially when switching from one app. to another, or after performing a function in an app (e.g. Save, or Delete in Finder). Messing around with the keyboard or trying another function often unfreezes the cursor again. It's frustrating.
I think it's probably a compatibility issue, since quite a few of the applications I transferred over from my iBook are not yet available as fat binaries ("universal" binaries). Yet they seem to work OK. I'll post about that separately.
If anyone else has experienced screen redraw issues, I'd be interested to hear about them. This machine should run much faster than my iBook, not much more slowly.

Thanks again, Shawn. I wasn't sure whether to post all the problems as one mess, or separately so people could search for them separately. I decided on separately, in case they weren't related, but mentioned the other bits in each post in case they were.
I myself searched under all these problems, but had little success. I don't know if that's an artefact of the Search or not. I suppose it depends on things like using "frozen cursor" or "freezing cursor". I certainly found more posts related to my problems when I read all the forum posts for MacBook Users. It took quite a while, but was more productive than searching. I'd rather not have to spend quite as much time on finding data, though.
Thanks again.

IDCS2 Screen Redraw issues

We're having screen redraw issues when panning and zooming pages. Getting screen anomolies and jittery display performance. It only happens when using InDesign, no other apps exhibit similar issues.
PC specs are:
WinXP Prop SP2
Dell Optiplex GX620, 2GB RAM
ATI Radeon X600, 256MB Video Card
Dual Dell 19" Flat Displays
Tried setting Display Performance slider in Prefs to middle setting and still getting redraw problems.
Is there a setting for the video card that might help?
Thanks,
-Danny

InDesign is known to have display issues with scrolling (white bars appearing where the edge of the screen used to be), although I don't believe I've ever seen it panning. As far as I know there is nothing you can do but grumble.
Not a lot of help, I'm afraid.

Screen refresh issue with SQL Developer 1.5.5 on Vista 64 bit

I am using the latest version of SQL Developer.
I have screen refresh issues in sql developer. On scrolling up and down the display gets jumbled, some time screen do not display at all. Its making working with SQL Developer very difficult. I don't have such an issue with any of my other editors.
Is this something specific to Vista? Is there any know solution to this issue.
Thanks
Edited by: user5899685 on Sep 1, 2009 11:14 AM

Specific? Not really, but judging from the posts here Vista is more prone. It usually indicates incompatibility between Java and video drivers.
If updating your JDK or video driver doesn't work or isn't an option, just disabling DirectDraw in \sqldeveloper\bin\sqldeveloper.conf usually works too:
AddVMOption -Dsun.java2d.noddraw=trueHope that helps,

Screen redraw / video card issue intel iMac

i've been having a screen redraw issue with an old-ish white intel core duo (not core 2 duo) iMac.
the screen will periodically show what i like to call screen dirt, and some of it is persistant.
i'm hoping it's something that doesn't require a visit to the apple store, as this machine is out of warranty...but it seems like it may.
perhaps someone out there has had a similar issue and can ofer some insight.
thanks.

Mac Pro 2007 with Nvidia 8800GT screen redraw problems on Mac OS 10.5.2

I seem to be having a slight screen redraw problem. Such as when grabbing the browser window and moving up and down it seems the redraw can't keep up,also seems problematic when watching flash or other video online. It does it in the finder too for windows listings or in icon view there is a fluttering or flashing back and forth, kind of like a white super split second flash when dragging the window box smaller or larger not as bad as when making smaller. Hard to describe but my original Ge-force that I pulled was not having these characteristics. I figure that the drivers need tweaking. In windows I am not getting these results. I have newer boot camp installed as well as the leopard graphics update done so I am trying to see if others are having a slight problem or maybe it is me.
Also I make certain it is not heat related as I monitor that and it does not matter at what temp it is.

Here's another similar experience -- and my solution.
I bought a Quad-core 2.8GHz (8GB RAM) Mac Pro in May and got the "better" Nvidia 8800GT. I thought I was happy, but there were redraw issues after sleeping and a display "roughness" I found annoying. Upgrading to OSX 10.5.4 didn't help.
I found it to be mostly absent on startup, but sleeping the Mac would bring it on. I.e., after sleep, the relatiionship between the 8800GT would be different than before. when I logged out and in again, the problem woud vanish. No what I expect from a "superior" graphics card. I ascribed it to funky drivers from Apple.
The store I bought the Mac from offered to swap for my suggestion of an ATI HD 3870, so I went for it about a week ago.
This card is far smoother than the 8800GT and just as fast in rendering benchmerks for graphics. (I'm not a gamer.) I am a happy camper! There is no stuttering, oddball redraw, or jerkiness as there had been with the 8800. It's perfect! Never mind that it may be 5% slower for gamers, it feels faster for my use.
BUT NOTE: As I now see from reading several forums, I wasn't alone is getting a screaming-Mimi at first! The first 3870 ran at nearly full fan speed at power-up. The speed changed a little with resolution changes on my big Mitsubishi CRT monitor, and actually stopped when I switched to 1080x1920 @ 72Hz! Then the fan would start and quit, start and quit randomly -- convincing me it was defective.
I returned this RED-shrouded unit and the store replaced it, this time with (randomly) a BLUE-shrouded unit. (Slightly lower serial.)
Bottom Line: This replacement 3870 is quiet as a mouse! Fan runs near-silently at startup and after hours of regular use in a 75ºF room. I get the distinct feeling that a bunch of cards with wonky fan controllers were built, and some of us got 'em.
Bad News: The ATI HD 3870 does NOT support multiple refresh rates under Windows XP-SP2 booting the Mac Pro, with or without Boot Camp drivers installed. No version of the ATI drivers fixes this, and ATI does not officially support Boot Camp yet. You can choose a resolution okay, but you're stuck at 60Hz refresh -- a pain for those of us who hate 60Hz flicker. (I like 100Hz refresh.)

Screen Redraw problems on 3.3

I am getting more and more disappointed with Apple products lately. I've been a faithful Aperture user since the rip-off $699 V1.0...
It seems that they are fading away from the Pro's as time goes by...
This upgrade is a joke. I have 334 Projects and 37000 Photos... The monochrome icons are hard to find, advanced features are gone and there I am experiencing slower performance...
I have a super fast 12-Core 2.66GHz Mac Pro with 1TB Accelsior SSD PCIe Hard Drive (I get 750MB/sec R/W Speeds) and use Photoshop CS6 Extended.
It used to take about half a second to open a TIFF photo in PS (22MP from a Canon 5D III or 16MP from Canon 1D IV). Now, it takes about a second. I know it might not mean much but I was used to speed and now it is slower...
My main problem is screen redraw. I have two 27" LED Apple Cinema Displays. One in Landscape Mode and the second in Portrait.
I keep my Browser on the left (horizontal) and the viewer on the right (vertical) screen... When hitting "Z" to zoom to 100%, there is a hesitation on the image redraw and I get 2 black borders to the sides of the image and like a half a second later the image is finally fully covering the screen...
This NEVER happened before.
I am a Pro and expect updates to be reliable. I need to work as fast as I can...
Apple is really starting to **** me off with bad releases. Everything seems to be geared towards consumer products.
They did it last year with Final Cut Pro and they are doing it now with Aperture 3.3.
Why do they feel the need to remove features instead of adding or improving them?
Why is it necessary to merge iPhoto library on Aperture? Pros and consumers should stay separate...
Next thing, they are gonna merge Final Cut Pro X with iMovie...
I do love the new White Balance "Skin Tone" feature... It works great.
I think I'm going back to 3.2.4 until they release a 3.3.1 update or better off, an over due 4.0. I hope I don't have to wait 3 years for it like I'm gonna have to wait for a new redesigned Mac Pro... I still can't believe the Mac Pro box is 9 years old, since the introduction of the G5...

Please don't rant, whine, or tell your personal tale of woe here. We are just users, like yourself. A number of us help others -- for no remuneration, notice, or status beyond our rather sad looking handful of dots. (I see you have the minimum .)
Apple is notoriously difficult to talk to. The approved channel is via "Aperture➞Provide Aperture Feedback". If you want to tell them what you think, that is the way to do so.
If you have specific problems or issues regarding Aperture that you would like some community help resolving, by all means post them here. Be specific and informative -- what is the problem? when did it start? how is what you see different from what you expect? what have done so far to resolve your problem? what effect, if any, have your attempts had? -- and edit out everything else.
Nice system, btw.
You might take a look at your Preview settings. Mine were changed without notice when I upgraded to 3.3. I don't see how this would necessarily slow down screen refreshes, but it might make it seem slower.
And -- just for buddy-buddy -- I used iMovie for three weeks straight a couple of years ago, then finished that project. I would rather get paid to wash dishes than ever use iMovie again.

Late 2012 Mac mini screen redraw problem

I have just purchased a new MacMini, basic model, and am experiencing screen redraw trouble. I run the MM headless, it's used as a file server and CrashPlan backup host for friends and family, administered/ controlled by using Apple Remote Desktop running on my MBP. For some reason the screen does not display correctly - I have to run the cursor over the screen, a bit like Etch-a sketch, to get the display to refresh.
Any ideas what may be causing the problem? I use ARD at work to administer the office servers and have not had this problem before, I also use ARD at home to control other computers.

Hello,
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

Premiere Pro CC, Quadro 4000 and Screen Redraw bugs

Not sure if it's just the 7.1 update, but i think i started seeing it in the previous version.
When i start using transitions then my main UI screen redraw messes up. So for example pop a wipe onto some footage then the timeline bar doesn't move when playing and i cannot click the sequence footage elements. I can play in the monitor. If i guess where the close box is for the sequence and open the sequence again it redraws correctly.
I've updated the drivers to the latest versions and also confirmed on a different PC that the problem isn't there. So it's unique to my set up.
I'm running on Win 7 x64, 32GB. About the only recent change to my system was a 10Gbe card but i've duplicated the problem just with local drives.
In fact it's as simple as if i start up CC then click the project tab, media browser tab, info tab, effects tab the search box in the effects tab doesn't redraw fully.
Any ideas what could be causing this?
(I do have a decklink extreme in there but have got the output turned off at the moment - tried it on and off- same problem)
I really don't remember this happening in the past but it was the transitions that revealed it, and i don't normally use them.
Help!
cheers
Paul

Thanks for the update,
The question is how long for because i'm sure that my installation was fine, then stopped working. If you drag a transition onto the timeline does the time line still update, can you grab the timeline cursor and drag it back and forth.
We're not alone, there's another thread with what looks like the same issues
cheers

How to get full screen caller pic in ios 7.1

How to get full screen caller pic in ios 7.1.Please help me

Haha .. I have seen one million post on this issue since 7.1 was released. Everybody hates it and it is perhaps Apple's stupidest design decision. I, personally, happen to like it ... or not mind it as much either way, I should say.
But that's not what you asked ... Apple thought it was best for some odd reason to change the full screen pics to an itty bitty circle. As a previous poster said, it cannot be changed. But be sure to go to Apple's feedback website and let them know you are unhappy about it. I sense an iOS 7.1.1 coming out REAL soon!

5.1.0 sp11 Connection pool refresh issue, revisited....again...!!!

java 1.3.1_01, 1xoracle 8.1.6, latest JDBC 2.0 drivers from oracle. Each weblogic instance and oracle have their own machines.
We do indeed have a firewall employed to run our subnets, and hence
our weblogic servers and oracle databses are in different DMZ's, but are
allowed to communicate to each other via rules set up on the firewall and
inspection of the logs show no such connections being dropped.
As far as the db is concerned, lookups (no writes) never take more than a few
hundred milliseconds and are then closed and given back to the connection pool
immediately from within the 'finally' block of code, hence hard to see when,if ever, the db is
is closing them due to excessive idle time.

Hi Joe,

Please find attached a copy of the jvm thread dump we got from thelast time
that weblogic blocked upon trying to refresh a broken connection.
We have turned off JIT with the environment settingJAVA_COMPILER=NONE.
FYI hotspot is enabled with '-hotspot', these settings can be foundin the
attached 'startWeblogic.sh'.Hi. I found a serious problem by reading the thread dump:
"ExecuteThread-11" daemon prio=5 tid=0x179d40 nid=0x19 waiting for
monitor entry
[0xeee80000..0xeee819e0]

- waiting to lock <f8e77ad0> (a java.lang.Class)
at com.akqa.sainsburys.jv_recipe.ejb.session.RecipeBean.getConnection(Re
cipeBean.java:759)
It is important to never call DriverManager methods in a multithreaded
application
such as Weblogic, because these JVM methods are alloverly synchronized
at
the class level. One such method, DriverManager.println(), is called
continuously
by all JDBC drivers as well as the SQLException constructor. If one
server thread
makes a long-lasting or hanging call to DriverManager.getConnection(),
it can halt
all JDBC in the whole JVM including work on other open driver
connections.
Please show me the code for RecipeBean.java, and I will send you an
altered version
that should solve this problem. In fact, I can infer from the thread
dump what is needed.
Change the one method getConnection() to this:
// Make once and re-use a driver instance directly, avoiding
DriverManager
Driver d = (Driver)class.forName("weblogic.jdbc.jts.Driver").newInstance();
public Connection getConnection()
return d.connect("jdbc:weblogic:jts:yourPoolNameHere", null );
Also, change your pool definition. I assume you have
testConnsOnReserve set to true.
(You should). Also, you should change your refresh minutes to
something huge, like
9999999. The refresh is interfering with your online performance and
is unnecessary
if you have testConnsOnReserve set. I recommend:
weblogic.jdbc.connectionPool.RecipeDBPool=\
url=jdbc:oracle:thin:@foo:1521:BAA,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=50,\ <------ note that this should be the
same as max, so all cons are made at startup
maxCapacity=50,\
testTable=dual,\
testConnsOnReserve=true,\
refreshTestMinutes=9999999,\
etc.
Joe
I've also attached some firewall logs around the time of weblogicblocking
(12.09). I could only get screen dumps for you, this may or maynot be
useful.
For the firewall logs use the following legend :-
195.110.64.205 - DNS
172.16.160.195 - host webserver 1 (i.e. what our licenses are boundto)
172.16.160.196 - host webserver 2
172.16.160.220 - website 1
172.16.160.230 - website 2

Apologies for any misunderstandings with my previous post, it appears to

Thanks for your time.sure, but first let's get you running OK. These dumps seem to be
very cryptic, as if you're running a highly optimized JVM that
loses almost all of the Java class references I'd normally see.
Can you run again with a more basic JVM? I am beginning to suspect
the JIT JVM...

Fequently however, connections are found to be broken
(either by periodical refresh - refreshTestMinutes or
testing connection before granting it to the
application - testConnsOnReserve=true), this has been
confirmed by viewing JDBC.log .
When this is so, weblogic attempts to replace these
broken connections with new ones and then proceeds
to grant it to the application. Once in a while however
(and by no means 'x' refreshes later), weblogic will not
come back.
One of 2 errors occur in our deployment which cuase weblogic
to refresh a connection.
<JDBC Pool RecipeDBPool> java.sql.SQLException: No more data to read fromsocket
and
<JDBC Pool RecipeDBPool> java.sql.SQLException: Io exception: Broken pipe
I believe these settings to all be correct, JDBC drivers
in the correct point BEFORE weblogic.aux in classpath, yet
still have the issue of broken connections.
Any ideas ? I've been reading a lot into this probelm
on various postings now, and i'm completely stumped.

Long posts in I.E. 8 refresh issue

Recently I've had to upgrade to I.E. 8 on some PCs I work with, and posting from them, I've noted the that editing long posts have refresh issues. I type and the cursor returns to the beginning of the post, and I have to keep scrolling back down. Is this a known bug? Or is there a workaround with I.E. 8?

Hi Dave,
I'm obviously far too tolerant of bugs. I'm running IE8 both at home and at work, but this has only ever happened on my work machine. I've meant to look into the cause before now, but I only notice when I'm in the middle of a large post and by the time I've got that out of the way it's usually time to deal with other matters. I've often just put up with the text snapping up and down the screen as I type, but occasionaly have started composing in Notepad or switched browsers. I've just implemented the fix so hopefully I won't need to worry again.
Many thanks,
tt2

Screen redraw jerky?

I've got an 2.4Ghz MBP running the latest version of Leopard that is maxed out with 4GB of RAM. I run XP under VMWare full-time. Most of the time, things are fine. However, at times my computer will just seem to "slow down", even when not much is running. I think I tracked down the problem to Google desktop, which I have uninstalled, and I haven't seen general slow-downs since then.
Then yesterday, all screen redraws suddenly became jittery. Dragging the mouse, pulling the dock up, even typing in Mail.app. I quit all programs, including VMWare and put the computer to sleep. This morning, the problem persisted, so I rebooted. Upon reboot, the system seems normal again. I would expect oddities like this on a Windows box, but not the Mac. Any suggestions would be appreciated.
btw, I run Time Machine most of the time, so I don't think the problem is related to that (if so, I would have seen the issue sooner).
Thanks in advance,
Ben

This link explains what you see on the Startup Manager screen,

On your Startup Manager screen, your only choice is your OS X volume, and not OS 9 if it is installed alongside OS X. For you to boot into OS 9, open your System Preference window & select Startup Disk. When the Startup Disk window appears, Os 9 & OS X should appear. Select OS 9 & you'll boot into OS 9 on a restart.
