Odd Screen Rendering Issue

Hello,
My iMac is displaying an odd screen rendering error that I so far have not been able to resolve. There is a black line that runs over 2" along the bottom right corner of the display. It does not appear when on the grey Mac boot screen, but shows up after log in. I tried to take a screenshot using CMD+OPTION+4 and the line does not show up. If you look closely at the picture attached you will see that the mouse cursor renders over the line.
I have all the latest updates installed. This iMac is also out of the AppleCare Warranty period.
Any recommendations on how to solve this would be greatly appreciated. I work in IT, so don't hold back on the technicalities.
Thanks,
Ken

As others have said, this feature is called "screen zoom". Hold down the control key and scroll up or down on your mouse to zoom in or out. Right now you are zoomed in. This also works on the trackpad.
If you don't want that feature enabled you can go to system preferences>mouse and uncheck "screen zoom" there.

InDesign CS4 - Serious Screen Rendering Issue

I just migrated from the CS2 Suite to CS4 Suite (I uninstalled CS2 Suite first before installing CS4 Suite) on my Windows XP SP3 system.
The first thing I noticed was that InDesign CS4 (ID) had trouble rendering its screens properly when doing common functions. When the issue occurs, only "parts" of the ID app screen will display (see attached figure), and the CPU usage (as shown in Task Manager) goes to 100% usage. At this point, my system grinds to a halt, and I don't know where I am in the ID application because the screen is not fully "painted". All I can do then is shut down ID using the "End Task" option of the Windows Task Manager. As soon as ID closes, my CPU usage immediately goes back to normal (5-10% range).
So far, I've noticed this rendering issue when:
- I minimize the app to the system tray, then go to maximize it. This happens with or without an ID file open.
- I am closing/exiting a file
- any time a lot of screen repainting needs to occur when moving "in" and "out" of ID
This issue may not happen at every instance in the above circumstances, but often enough (90% of the time) to make ID virtually unusable to me. Sometimes, I am able to "jog" ID back to its senses (i.e., a proper repainting of the screen) by navigating through the ID menus. This works only sporadically, however, and the results usually do not last long.
This issue does not show up on any other of my CS4 apps (PhotoShop, Illustrator, Acrobat, etc.), nor on any of my Windows Office 2003 apps. My other colleagues in my department have not seen this issue with their CS4 ID, and some of them are running nearly identical systems as mine (everything but the Dell monitor).
What I've tried so far without any help:
- used Adobe Updater for the latest CS4 updates (I am running ver. 6.0.2 of ID)
- ran Windows Update and installed all the latest updates beyond SP3
- deleted files on my hard drive to free up space (I have 20% free)
- defragged my hard drive
- updated my display driver
- tried various screen resolutions and refresh rates of my display
Specs of my machine:
Dell Optiplex GX620
Pentium 4 3.00 Ghz CPU
80 GB Hard drive
4 GB RAM
Windows XP SP3
Dell 1907ftp LCD monitor
IE ver. 6.0.2900
McAfee 3.6.0.608 virus checking
Can anyone help?

One thing that is missing from your list of system components is the video card used on your system. And that may be the source of your problems. In general, though, we are not aware of any video problems particular to InDesign 6 as opposed to InDesign 4 which you previously had installed.
Many low-end computers from Dell and others take the low cost route by integrating a graphics display chip, typically from Intel, on the motherboard which does not have its own dedicated graphics memory. It shares memory with Windows. This has several ramifications (pun not really intended, sorry!). The first is that using main memory as video memory means that you have very slow video memory, very much slower than the memory on dedicated graphics cards. The second is that access to that memory competes with disk operations, CPU operations, and virtually everything and anything going on with your system. If in fact your system does have one of these integrated graphics chips in lieu of a real graphics card, there might not be much you can do assuming you have the latest video driver (you said you checked that) unless your Dell OptiPlex allows you to disable the motherboard integrated graphics chip and install a real video card. (To be completely fair, the integrated graphics display chips are perfectly fine for systems that are not running graphically intensive applications - Outlook, Word, and a web browser instance or two work quite well with those configurations.)
Other things that I would check would be disk space as well as fragmentation. An 80GB disk is not that big these days and if most or much of the remaining free disk space is highly fragmented (as it might be after uninstalling CS2, installing CS4, and perhaps doing a whole bunch of Windows updates including SP3), disk operations, including page file operations, might be excrutiatingly slow.

Tebuchet screen rendering issues in Acrobat

I have created an information sheet using MS Trebuchet on the Mac in InDesign and exported to PDF. When viewing the PDF the font does not display correctly, some area looks bold. If you change the percentage zoom page size the font changes. It look fine at 130% but at 134% some of the sentences in paragraphs look bold?

I have been in discussion with a typographic designer who suggests it may be a combination of Trebuchet not being a ClearType font and therefore old technology and the text styling not being clean when the text is copied from Word into InDesign
Urm, both of those suggestions are gibberish absurdities.
First, whether a font is "a ClearType font" is just a question of whether the font's hinting is specifically optimized for ClearType. Non-ClearType fonts work fine under ClearType as well, and in any case Acrobat doesn't use ClearType at all—it uses Adobe's own font rendering technology.
Text styling is only an issue when the text is styled to a non-existent font. For example, you style some text bold, and there is no available bold font. This is only a problem in applications that allow such "faux" styles and try to "simulate" the bold or italic effect. But InDesign doesn't allow faux styles, hence there is no way that there could be a faux styling issue in a PDF made from InDesign. (I imagine there are ways to get faux styles into Acrobat, especially if the fonts aren't embedded, but I'm not sure I've seen it, aside from Acrobat's own substitution fonts. But none of that is relevant here.)
So I don't know what the problem IS, but I can tell you with some certainty that those are two things it IS NOT.
My first thought, like Dov's, was that it was some sort of transparency and flattening issue. But the details of where the text is and which text is affected make that seem less obviously plausible. Still, you might try as an experiment deleting the object(s) with the drop shadow on that page and seeing what happens. Or even copying that text box to an empty page.

Odd screen corruption only with admin account?

I hope this is the right place to post this. I'm having an odd screen corruption issue on my Mac Pro 2.0. As the cursor passes the mid point of my midpoint of the screen, the screen will "jump" or "shift" and add a row or column of pixels to the monitor. Any text or graphics around the these newly created rows will become corrupt or appear doubled. Also the cursor will behave very oddly. When rolling over a text field in an application sometimes the arrow won't convert to the text entry icon, the entry icon will appear superimposed on the arrow icon.
At first i thought it was a hardware issue (video card going bad ) but Hardware Test came back clean. As a last resort I created a new user and voila! the corruption goes away when logged in under the new user! I'm assuming there is a corrupted file somewhere associated with the admin user account. Obviously I can't delete the user as it's the owner/admin account. Any place I can start looking where the offending file might be found?
Mark

Hmm, I've got screen zoom turned off so I don't think that's it. Now some of my icons are coming up corrupted,but again, only when I'm logged into my admin acct. Is there a preference file that in the user/~/library/preferences file that i could toss and see if it helps? I could always just toss the whole preference files folder after backing up and then try replacing them one at a time but I'd rather not do that if I have a choice.

Java script issue on screen rendering for all-11-otn4.js

Hello,
I am getting java error on screen rendering for all-11-otn4.js line no 12277 and 16073. The java script error I get is, *"A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in debugger, or let the script continue"*. After this page stops responding, i have to close the browser and reopen it.
I have a table inside my screen. The table is added inside a af:panelCollection and have few toolbar buttons added inside the secondayToolbar facet. This error is commng due to the table toolbar buttons.
When i check the java scirpt using debugger, it stops at following java script at the bold line,
AdfUIComponent.prototype.getParent= function()

var x148=this._peer;
if (x148!=null)

RX9800PRO 128MB Rendering Issues

I recently purchased the MSI RX9800Pro 128MB card from newegg. On initial install of the catalyst 4.7 drivers everything was well. I am upgrading from a Geforce 4 Ti4600, so it's should be quite an upgrade, yet I have 2 issues. (i did a full uninstall of the NVIDIA drivers before installing the new card).
1. After about 30-45 minutes of playing a game, I get VERY wierd geometry errors. Like suddenly walls are protuding outside into nowhere, textures are streched beyond what they should be, etc. I have a screenshot of Starwars Galaxies if anyone needs an example. This is the issue i care about.
2. I don't really notice a speed increase, I don't have any benchmarking tools installed for before and after. This issue could just be my imagination though. (you always think new purchases are ganna be a magical change )
I'm running an Intel 2.4 Ghz, 1GB ram, on an Asus P4PE motherboard. i'm using the onboard sound and ethernet. I have a DVD-burner, floppy, and another DVD-ROM drive. 2 hard drives, 1 CPU fan, and 2 case fans, 2 fans are attached to the motherboard power, 1 fan is attached to PSU molex. It's in an Antec case, with the Antec SL350 PSU. (+5V/35A +12V/16A +3.3V/28A), output of 330 says the label. I'm running Windows XP SP1, on the latest ATI 4.7 drivers. Also i have the power connector from the card plugged into a dedicated molex out from the PSU. I hope that covers all the specs you'll need
So is this card defective or am i just demanding too much out of my PSU? Would disconnecting the DVD's/floppy/fans help to determine this?
Thanks for any help in advance, i love this card thus far and would hate to have to return it!

I definitly dont have the time or patience to reformat, nor should i have to, nor do i think it will help. I think it is related to heat issues, yet the card never gets hot as i think it could. I can still touch the heatsinks, granted it's very hot, but it won't burn me.
But the reason i think it's related to heat is because games will be fine for some time while i play them, then suddenly i'll start to see a patch of messed up pixels all throughout the screen, then the geometry rendering issues start to appear on new loads of levels/characters. I've even tried opening up the case and putting a external fan right on it, I still get the issues.
It's odd tho, nothing ever locks up, and 2d always works fine. Might I have a defective card? i have done endless searches and cannot find one other person who has this same issue.

Small screen rendering bug

There is a very subtle rendering bug when overlapping text.
I'm not sure if this bug is worth fixing, as depending on how
Mars rendering is implemented, it could be very difficult to fix.
When overlapping to sections of text, the anti-aliased pixels
will compound between overlapping lapping lines. This leads to a
slightly "heavy" look at the point of overlap. This most affects
double-layered / slightly-offset text used for shadowing, as the
outlines of the two text areas match closely. It affects screen
presentation and not print.
The easiest way to demonstrate this bug is to copy and paste
a text node multiple times into the SVG document. The rendered text
will darken each time, until eventually, the text has a hard,
jagged outline. The affect is easiest perceived with smaller font
text because the ratio of anti-aliased pixels to 100% "solid"
pixels is greater.
The preferred behavior in this case would be to pick the
darkest color point for that pixel from among all the overlapping
anti-aliased pixels for each channel of color. The resulting
anti-aliased pixel layer would then need to be blended as normal
with any other overlapping layers... This could be tricky, but I
think it would increase the overall quality of screen
rendering.

Unfortunately, this bug is pretty much beyond our control.
Pixel-level rendering issues like this are handled entirely within
the Acrobat core -- our plugin parses Mars SVG, converts it into
Acrobat-friendly data structures, and then hands everything 'over
the wall' for the Acrobat core to render.
We have some control over the renderer's low-level settings,
and I hope to exploit that in the next major release of the Mars
plugin to take care of some other pixel-level rough-rendering bugs
we've been seeing. However, this particular bug looks way too
subtle for us to address with the level of renderer access we're
given ...

Font rendering issue in Windows 7 with Aero

I'm running Windows 7 Home Premium 64-bit, and using Firefox 19.0.2. Aero is enabled, but the ClearType font smoothing is turned off.
At completely random intervals, text is rendered like this in Firefox:
http://i49.tinypic.com/vgshv4.png
Sometimes it can be fixed as simply as hovering the mouse pointer over the affected parts. Sometimes I have to mark the text to get it rendered correctly, and sometimes it can be fixed by scrolling the page.
It can happen on any sites with any encoding, regardless of the font size and color, but I noticed it's extremely rarely happens with Japanese text. It never affects the whole page, only random parts of the on-screen text, and sometimes the interface text as well. Also worth mentioning that it never happens when Aero is turned off.
Is this a Firefox bug, or is something wrong with my system? Thanks in advance.

I had the same issue, uninstalling windows update kb2670838 fixed it for me. See also:

Captivate 6 rendering issues when publishing flash only

Hello,
I wanted to ask if anybody else is experiencing the same issue as I am experiencing when I publish my captivate 6 projects:
Issue:
Project consists of 46 slides. No advanced actions. Multiple rollover images and text captions are on several slides. software capture
When publishing to a USB or my desktop then previewing I get rendering issues and these vary from parts of the software that I am capturing not appearing at all to my master slide templates disappearing. Whenever this happens I try publishing to flash 10 and ctick the force republish of all slides - sometimes this fixes the problem sometimes it does not. So I try publishing to flash 9 force republish of all slides sometimes this fixes the problem sometimes it does not. It is just so hit and miss I have to publish 4 to 5 times before I finally am successful. So of course this is extremely frustrating when I have to make changes to the project and republish.
Also notice that viewing in web browser has the same issue.
Think I am going to have to go back to captivate 5.5, which is such a shame as I really love some of the new features in 6.
Does anybody have any ideas as to why this may be happening?
I have attached two screen dumps - one where the screen is rendered poorly and the other where I have crossed all of my fingers and toes and republished and the screen has been rendered correctly:
Thanks
Ali

Hello Sankaram,
I am experiencing the same problem as Ali, where my master slide randomly disappears in my published project. I tried the options you listed above. I also deselected "Use Master Slide Background" and "Project Background" on each slide.
Also, I have a button on each slide (next button to move through the slides) and sometimes disappears as well. However, I can still click in that region where it should be visible, and it will progress to the next slide.
Any suggestions?
Thanks,
Jackie

T400s Screen Color Issue

Anyone have a color-mismatch issue? T400s screen is at factory default but the colors are definitely different from desktop screen rendering. Have tested photographs on different screens and the T400s is much cooler (less red). Also, hypertext links are a lighter blue on the T400s vs. more blue/purple on the desktop monitor. This has been tested on a Samsung desktop monitor, a MacPro laptop, a Dell desktop monitor. All are the same except for the T400s.
Any comments are appreciated!

Hi sdreyer,
Welcome to the Lenovo forum!
Color perception is a fascinating subject, you can find more about it and monitor calibration at this post and the links therein.

IPad Game Rendering Issues

I just downloaded Infinity Blade today, and about 10 minutes into the game, I realized my character and any opponents I faced have rendering issues. Their shading an color is of, and the colors sometimes flicker. This happens in every single video, battle and screen. I've restarted the iPad three times, and completely shut down the game & other apps. I also noticed that when I turned the iPad back on, the screen flickered right before showing the lock screen. What should I do? Is this a problem with the A5 processor?

Try a reset of the iPad.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Outlook 2013: Memory smudge, or screen rendering problems due to laggy?

Hi,
I am observing a strange occurrence among some of my users with Outlook 2013. When they open a few new emails, whether they minimize or switch to another emails to read, there is some portion of the previous emails left behind. It is like a digital
smudge of the previous screen left hanging there. It will go off after awhile
This guy has the same issue as me:

I don't have a screenshot yet, but I was wondering
if this is due to lack of memory.
Thanks.

The answer given in the link you referenced is the most likely solution to your issue as it is often caused by the graphics card driver.
Make sure you have the latest driver installed and if that doesn't solve it, disable the hardware graphics acceleration.

Rendering Issues Windows XP

Hi,
I am completely stumped with a repaint issue in my app.
The application is a fullscreen app. There are JDialogs which appear on top of the main fullscreen JFrame from time to time. All windows are undecorated!
The problem is that sometimes the dialogs do not show and sometimes it looks like they do not disappear after being closed. However, if i rub my finger over the screen (touchscreen) then bits of the dialog will either appear/disappear as appropriate. That means it is a rendering /repaint issue ..
The times when this problem occurs are extremely random. Some installs may not notice for upto one year then it could happen a few times in a week..
All of my GUI code is called from within the EDT thread and i use the swinghelper class CheckThreadViolationRepaintManager to ensure that this is always the case. This should mean i have no repaint problems such as are happening. The EDT is not stuck either when these repaint issues occur as i monitor that to ensure this.
I also set the flag -Dsun.java2d.noddraw=true which i have read can fix some rendering issues on win32 installs. However this does not appear to fix it in all situations.
My biggest problem is how to debug this? Are there any other reasons why this might happen?
Thanks in advance..
BTW: the majority of the jvm's this happen on are 1.6_16 but i also have one running 1.6_22 (latest i think!)

I already wrapped any calls to JDialogs.setVisible(true) with SwingUtilities.invokeLater
I did this even though they are all created and shown on the EDT as they are called from an ActionEvent handler (can the actionevent generated by clicking a button be called from something other than the EDT? As far as i am aware it cannot).
i have frequent checks in code to check if we are running on the EDT and log a warning if we're not. When this issue occurs there is no warning in the logs about not being on the EDT anywhere!. I use SwingWorker where necessary to take any extra load off the EDT.
JDialog.toFront() should not do anything since it is modal (APPLICATION_MODAL) so it should be on top anyway.
This would only be something todo with showing the dialog. Not closing and then repainting the main frame behind it. All calls to JDialog.dispose() are wrapped by java.awt.Window.doDispose() to be on the EDT even if they are not called from the EDT.
These are all standard Swing/AWT repaint issues that i am aware of. Is there any other non standard ways this issue can arise?

StageWebView rendering issues

Hi,
I’m struggling with some problems in my flex mobile project.
On the Sony Experia S there are some rendering issues while interact with the StageWebView. As soon as I initialize a website or playback a video the whole screen around the webview area starts to flicker. To verify the problem I build a clean mobile app.
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView"
creationComplete="view_creationCompleteHandler ( event )">
<fx:Script>
<![CDATA[
      import mx.events.FlexEvent;
      public static const URL:String = "http://www.youtube.com";
      private var webview : StageWebView;
      private var r : Rectangle;
      protected function view_creationCompleteHandler ( event:FlexEvent ) : void {
          var ww:StageWebView = new StageWebView ( true );
     r = new Rectangle ( 100, 100, 800, 500 );
     ww.stage = systemManager.stage;
     webview = ww;
     webview.viewPort = r;
     webview.loadURL ( URL );
]]>
</fx:Script>
<s:Image id="backgroundTabBar" left="0" bottom="0" width="100%" height="68" scaleMode="stretch" source="@Embed('assets/img/background_tabbar.png')"/>
</s:View>
I recognized as soon as I set the android:hardwareAccelerated parameter to false the flickering stops. But I can’t set this parameter to false because the StageWebView is used to play videos.
Is there any known workaround or can someone give me a hint to solve the problem?
If it helps I can capture some video of the flickering effect.

Switching users causes screen display issues

I've had a new MacBook Pro 2011 that came with Lion on it. It's been working well, I migrated my old user accounts from my previous MacBook with Snow Leopard on it.
After having it a few weeks my son tried using the fast user switching and going into his account but the screen was exteremly glitchy. It basically show what looked like my users screen and would erase and paint with his correct screen as he dragged windows around. Eventually his screen would like correct then spontantously revert to showing my screen again.
Fast user switching back to my account showed everything correctly. Logging us both out and logging him in alone works fine. Logging him in first and then switching to my user gives me the problem he experienced of seeing mostly his screen and having to drag screens around causing re-painting to show my proper screen.
Screen refresh issue aside if we can work through messed up screens the computer appears to be working fine, apps launch properly and no sign of any memory or file corruption, everything "works" properly.
I tried completely removing and re-creating his account but the problem remains.
Couple of factors in case they are relevant.
1) We upgraded the HDD to a SDD but it shows not signs of any issues
2) We upgraded the memory beyond the normal limit of 8gb to 16gb using a Cruicial memory kit certified for the MacBook Pro.
3) We have both the laptop screen 1680x1050 running and an attached thunderbolt display AND a usb DisplayLink adapter to a 3rd Dell 1600x1200 monitor.
My intial thoughts were with the DisplayLink adapter. I made sure to get the latest drivers from the display link web site and did some searches but no one has described my problem.
The screen issue seems to present itself mainly on the "main monitor" the 27" thunderbolt display but we have seen some screen corruption on the MacBook LCD. Oddly the DisplayLink always appears correct.
Anyone have any ideas?
System Version:          Mac OS X 10.7.3 (11D50b)
Kernel Version:          Darwin 11.3.0
Boot Volume:          Macintosh SSD
Boot Mode:          Normal
Secure Virtual Memory:          Enabled
64-bit Kernel and Extensions:          Yes
Time since boot:          21:31

As a followup. Experimenting seems to suggest that removing the driver for DisplayLink cures the issue. Going to test more with reinstalling the driver and just unplugging the USB cable before switching.
Was also seeing (before uninstall) issues with getting a Beach Ball freeze during logout of the 2nd user.
I want to be certain of if it's the DisplayLink driver but once I am certain I'll take my gripe to their support forum.
