Xperia Z2 4k Camera causes screen flicker

When recording in 4k on my Z2 the screen flickers. This us also shown in the playback!

No,the internal memory is faster so there should be no problems.Did you try safe mode?

Time capsule causing screen flicker/"ripple effect" lines on MBP

When I wake my MBP up from sleep mode, time capsule sounds like it's waking up to, then it does a backup and when this happens this flicker/ripple effect/wavey line quickly races across the top of my screen a few times then goes away. Has anyone ever heard of this? Also is it normal for time capsule to be warm all of the time?

From what I've read on different posts regarding video card issues and the early 2008 15" MBPs, or "affected models", Apple seems very selective at what they'll honor for repair. Hopefully my MBP will be repaired under this recall, but am not holding my breath.
My 15" MBP (early 2008 Penryn) has developed video card issues I suspect. It doesn't do the dark screen as others have which Apple is more likely to repair under the recall, but random batches of lined patterns show up on the display, it will blink sometimes, then it will totally lock up forcing a hard shut down with the power button.
I took it into a local Apple Authorized Service center, they ran the NVIDIA test on it which it passed, showing that the "known" defect wasn't the issue with my computers video card. Well something's screwed up with the video card most likely. They recommended taking it to the Genius bar at the Apple Store which I plan to do. It's less than 3 years old, Good grief!
I've been an avid Apple user for over 16 years, and have hardly ever run into hardware issues. Guess I've been lucky. But how Apple will handle my MBPs issues is unknown to me. Hopefully it will be positive, but am not holding my breath.

Adaptive Portlet Causing Screen Flicker on Dropdowns

I have a Master Portlet displaying a Datagrid with a Hyperlink column in it that raises a PCC event for an Adaptive portlet. The Detail portlet has a series of DropDown list boxes. When the user clicks on the link to call the PCC and the detail renders the data, the drop downs flicker as if they are posting back, When the user clicks on another link, the drop downs flicker twice, another click, they flicker three times and so on. Anyone else encouonter this?

Your underpowered system may get by if you edit SD DV material, but is way out of its league when editing AVCHD or Red or DSLR material.
Without further info to go on, you have the following problems:
Not enough memory
No dedicated nVidia video card
Insufficient PSU
No hard disks
About the only thing good about your system is the CPU, but there it ends. Everything else needs to be improved. How much depends on your source material, your workflow, your destination format and all those data were severely missing.

MP 17" Screen Flicker - possible cause ?

Have had the MBP 17" for two weeks now, love it. Last night I calibrated the display with a Spyder 2 and in doing so disabled auto-screen brightneas in prefs. Since doing that when the display dims I notice screen flicker - similar to what you'd see on a display with a 60hz refresh. Enabling auto brightness again and the issue disappears.

Brand new MacBook Pro with Leopard and brand new 23 inch cinema display… I just saw some very noticeable screen flicker on the desktop picture. It was most noticeable when I had lots of windows open and could only see about an inch or so of the desktop at the top. It lasted maybe 5–10 minutes and stopped.

Macbook pro retina screen flicking problem

I bought this 15 inches Macbook pro back in Nov, 2012. And I have the screen flicking problem in Dec.
The problem is the same here listed on youtube. You can find hundres of them just by searching "retina flicker" on youtube.
http://www.youtube.com/watch?v=Ko6WCqw20ZE
And I did a lot of researches on this. I had also gone to the Apple Store 2 times, one Genius Bar Staff told me this has to be a hardware problem and offer to fix my laptop, others said it might be a software based problem and adviced me to wait for the new system update. I don't have time for a long fixing so I chose waiting. That particular one who told me to wait for the next software update also encourage me to dig deep and tried to find the root cause by myself...and I did. I found my screen flicking problem could caused by cellphone inteference. And It seems that the Wi-Fi antena is also a key component here. If I turn off Wi-Fi completely, the flickering went away.
Some solutions I found online
1. It can caused by Enable Safari webGL. So disable webGL and turn off develop mode
2. Disable displaycard auto switch in Power saving tab
3. Close the lid put the sytem into sleep and re-open the lid
4. stop using Wi-Fi. That's right people, try disable Wi-Fi!! It's the only working solution for me.
5. It could be caused by CDMA cellphones including US Verizon brand cellphones and many others. GSM cellphones are OK. Try to turn off your cellphone or drive to a empty plaza and try to see your laptop still flickering at your car. Turn off your cellphone when You do this.
What doesn't work
Reboot
reinstall OS
go to Apple Store and change Logic Board (Someone reported that after logic board change, the problem came back after a while)
Let me know if you guys have any findings, Thanks!!

I'm sure that you've seen the problem with 'burn-in' and 'ghosting' on some MBP-R machines in threads on this forum. It doesn't seem to be an overwhelming problem, but some have reported it.
Did you buy it from an Apple Store or online? Either way, you need to get tough with Apple. Tell them you need to keep your computer and, when they deliver a replacement to your local Apple Store, you'll bring it in for exchange. That's what they've been doing with most people that have had MBP-R problems - I've never heard of them requesting that you send your computer back before they will exchange. Did you contact your local Apple Store or was this response from an AppleCare phone conversation. If the latter, take it into the Apple Store, explain what you want to do, and I'm sure that they will work with you.
Good luck,
Clinton

Qosmio F10-124 - Pixelated screen, flicks into blank, then comes back to normal

It looks like the graphics hardware has failed on a pc bought in April 2005.
This occurred in stages, starting from around the time when I received
1) An automatic download of windows updates and
2) And Adobe upgrade.
In Sept 07. Do not know if this is at all related with the screen malfunctioning.
The screen has at best operated intermittently, with only access being possible using the external VGA port.
The latest Toshiba screen drivers for the WMD operating system did not rectify the problem.
In the last couple of days pixilation has occurred in various parts of the External monitor screen, whilst the laptop was just blank, up to that point the external screen was displaying my work just fine. Occasionally the laptop screen flicked into life and the pixilation has become more prevalent recently. The occurrences of the laptop screen working were random.
I need to have the screen settings such that the external monitor is a mirror of the Laptop screen to do anything on the laptop.
Rebooting the PC has no effect.
The latest symptoms are that the external screen shows that the OS has booted, but there is an alignment problem causing a pattern to appear across the screen, and this is "ghosted" ?? with several iterations of all screen events across the width of the screen output. The Laptop screen is not working at all at present.
Anyone have any ideas what could have caused this, and/or how to fix it??

The graphic card chip seems to malfunction. Your described issue sounds really like a chip fault
But please note that this is only my personal assumption and if you want to be 100% sure whats wrong then you will have to contact the service provider in your country for a detailed check.
In worst case the motherboard must be replaced because the GPU chip is fixed on the motherboard and cannot be removed.

Screen flicker on Macbook

'm on a Macbook (Intel Core Duo 2gHz Processor, 1Gig of Ram, 10 gigs of space left on an 80Gig drive).
The issue is that, at seemingly random times, my screen will flicker, as if the power management was trying to dim the screen during a period of inactivity period.
I called Apple support and they told me to:
1) Disconnect the power
2) Remove the battery,
3) Hold down the power button for 5 seconds
4) Reconnect the power and the battery
5) Power up, and when the system started to boot, hold down ALt-Option-P-R until the second boot cycle.
At first, it seemed to work. The screen flicker stopped. However, now when I boot, I get a grey screen of multi-colored vertical lines, and I need to Alt-Opt-P-R each time to get into the OS.
And, as of yesterday, the screen flicker is back.
I have no ambient light detector like the Macbook Pro, so I know that's not it. I've not seen any other reference to this on the web, so I'm stumped.
Thanks for any insight you might have.

I've experimented a bit, and I've found that the screen usually starts to flicker when the computer is under high load, such as playing a few YouTube videos, or playing a game.
When it started flickering for me, I was running on battery power. My first theory was that the battery could possibly not be supplying enough power to keep everything going (even though it was > 50% charge), but then one day I started getting the flicker while I was plugged into the power adapter. I could still be that the MacBook's hardware is requiring more power than it is getting, but if that were the case, more people would be having this issue.
The flickering doesn't really annoy me that much, as it only lasts for about a minute or two at the most, and it seems to come around once a day or so. It does worry me though, the way in which it flickers doesn't seem good -at all-, and I'm afraid that one day the screen will flicker and it'll get stuck like that, or even not turn on properly again. With my luck it'll be the day the warranty runs out.
As of right now I can't afford to part with my laptop either, as I also have school.
Hopefully someone finds a software fix, or Apple figures out the exact cause of the problem so it can be sent in for a quick hardware fix.

Screen flicker..is everybody experiencing this?

before i soon go out and buy the mba 13",
can any body say that they are _not experiencing_ the screen flicker when scrolling issue.
if everybody is,
is apple expecting this to be regarded as normal?

The 10.6.5 update fixes the flicker issue that some users experienced after waking their MacBook Air from sleep. The flicker issue that "ashhast" is asking about is unrelated, he's asking about the flicker while scrolling issue. As far as I understand, this issue is caused by a problem in the hardware that can not be repaired through software. I personally am experiencing this issue on a 13" MacBook Air (and have installed all the software updates available up until today, December 17th). You could take a look at the thread "Flickering screen when scrolling" started by "nonicoclolasos" for some more information:

Lightroom 5.2RC Screen Flicker in Library Grid Mode

Hi,
Having a screen flicker problem since 5.cRC came out, but only in Library/Grid mode when scrolling or selecting from the grid. But only when there are more images than can fit on one page in the grid.
Seems to use an unusually low amount of memory with nothing else running on the system.

I've been having the exact same problem with Lightroom 5.2. I also have an Nvidia card, a GeForce GT 610, and driver version 327.23. One additional part of the problem is that I can hear almost constant disk access when in grid view mode in the library module. That seems to be related to Lightroom refreshing the display as I scroll down through the images. On newly imported images, it takes about two seconds for each thumbnail to just display the keyword symbol in the lower right corner. After the first time scrolling through all the images, it goes a bit faster. Even then, CPU usage goes up to 80% just by selecting a new group of files.
It almost seems like something is making it take a long time to build each thumbnail and sync all the information that's associated with that thumbnail before it will let you do any other work with it. I don't think it's really associated with the dislay driver. I never had this problem with LR 4.4, it's just since I upgraded. I also never had an ealier version of LR 5; I went right to 5.2 from 4.4.

Screen Flicker on one side

Hi, I use an HP Mini 210-1099.TU. It has served me very well so far but since a few days the right side of the screen doesnt stop fickering. I have tried system restore to an earlier date and taken all steps as advised by 'Windows Help' regarding brightness but nothing seems to work. Kindly guide me as to how this issue can be resolved.
Thank you!

Dear Customer,
Welcome to HP Support Forum and we are glad to assist you.
Whether your laptop screen flickers occasionally or continuously, it's not only a distraction but it could mean that a hardware problem has developed. Troubleshooting the exact cause of a flickering screen can be challenging, but the cause may be something as minor as a loose cable
The inverter board provides the laptop's backlight lamp power. It does this by converting AC current to DC. If the inverter board is shorting out or failing, it could cause your laptop screen to flicker
The backlight lamp provides light to the LCD or LED laptop screen. LCD laptop screens generally use CCFL backlights, while LED screens use LED backlights. Your laptop's screen may flicker if the backlight lamp is failing or if the power cable from the inverter board is not securely connected
Step 1
Change the refresh rate to match the capabilities of your monitor. The refresh rate is a measurement of how many times the screen redraws each second. Although this setting is related to older, desktop monitors, it can affect the quality of the Liquid Crystal Displays found in laptops. Right-click the desktop and choose "Screen Resolution," then click "Advanced Settings" and "Monitor." If enabled, place a check beside "Hide Modes That This Monitor Cannot Display" and choose a higher refresh rate from the list.
Step 2
Update your graphics card drivers. This is the most likely cause if you've always had a problem with flicker. Look for "Hardware and Sound" in the Control Panel and click "Device Manager." Under "Display Adapters," you'll see the exact brand and model of your video card. Go to the manufacturer's driver Web page and search for this model to download the appropriate drivers. Alternatively, you can revert to an older driver if the flicker began immediately after an update. In this case, return to the Device Manager, right-click your adapter and then "Driver." Click "Roll Back Driver" and "Yes" to confirm.
Step 3
Turn on Vertical Sync if the flicker occurs when DirectX or OpenGL is in use, for example, while playing a PC game. Vertical Sync, or VSync, locks the refresh rate of the application to the refresh rate of the monitor. Horizontal flicker is reduced, which improves image quality. For Nvidia cards, VSync is found in "Manage 3D Settings." For Intel, look for "3D Settings" or "Asynchronous Flip." On ATI/AMD cards, turn on "Wait for Vertical Refresh."
Step 4
Lower and raise the laptop screen repeatedly to determine if the flicker is related to movement. Hardware failure is the likely cause when flicker occurs only when the laptop moves. Most likely, the screen cable is loose or damaged, but the inverter and backlight can also cause this problem. The laptop needs to be opened in order to confirm the problem, but do not attempt this unless you are familiar with PC repair and do not mind voiding the warranty. For the best results, take the laptop to a licensed technician or send it back to the manufacturer.
Hope this helps, for any further queries reply to the post and feel free to join us again

CS5 AS2 mac projector screen flicker–no flicker from CS3 projector

I've been working on a flash project for a while using a G5 PowerPC, 10.4.11, Flash CS3 using AS2 and publishing a mac projector/Windows exe. Mac projector has always worked fine. So has the exe. I just upgraded to an iMac, Snow Leopard 10.6.8, AMD card and Flash CS 5.5 v11.5.0.325.
I'm using the same CS3 AS2 flash file from the old G5 CS3 setup on my new Snow Leopard Mac CS 5.5 setup. When I publish it, the mac projector flickers like crazy. It looks to be an animated png issue. But I have never had that problem on my old slow G5 - the projector always played perfect, no flicker.
On this CS5.5 generated projector, the flickering occurs on the splash - large png files, but my G3 never had one issue. Also, my small png rollovers flicker - not just the animation. And the screen flickers non stop when there's no mouse activity.
I copied over a backup of my CS3 generated projector onto my new computer and played it to see if it was a graphics card issue. No flicker! The CS3 projector plays perfect on my new Mac. All content within the two projectors are identical - What gives?
Why is CS5.5 generated projector flickering, but the exact same file from a CS3 generated projector works perfect on BOTH computers?
I've spent several hours searching for the answer but can't find a flicker issue similar to mine.
I don't have bitmap caching enabled. I didn't change any of the default settings in CS5.5. I just copied the CS3 file to my new computer and published it, then I got instant screen flicker. I don't know what other settings to change for projectors. Never had performance issues with projectors or exe files, no matter how old the computer was that was playing the file.
This must be a Flash setting issue, but I can't find it.
By the way, the cs5.5 genertated exe file plays like a champ - no issues.
Ideas?

I also tried publishing the projector in flash player 9 and 10 to see if that would make a difference. It did not. I was publishing in flash player 8 on my old G5 computer and that's what I published it as through CS5.5 as well. That didn't work either. I'm search for some sort of fs command AS2 issue when using CS5.5 to see if I need to change the code, but have not found anything yet.
It's the full screen mode that is causing the flicker though - only when published from CS5.5. Full screen mode works out of a CS3 projector on both computers.
Screwy.

10.4.6 Causes photobooth Flicker

Just posted further down the page. I just installed 10.4.6 and when I launch photo booth the camera flickers like it is adjusting to the light--never used to do that at all.
I also have the effects page slow down to slow motion when I click on it.
****!

I too have updated to 10.4.6 and am experiencing the same flicker problems in photobooth, interestingly, I read your message before i updated and it worked fine. Having just updated the flickering has started and it is exactly how you describe it. I think Apple need to be made aware of this issue as my little experiement proved that it IS the update that is causing the flicker. Any suggestions

27" Screen Flicker

I just got my new 27" i5 today. I am coming from a PC so I had it on all day watching the online videos and tutorials. The computer was flawless all day. I love it buy the way
This evening the family turned on the TV so I plugged in my headphones into the jack in the back and started back looking at the tutorials. Shortly after I started to get the dreaded screen flickers. I thought I was seeing things because the computer had been so great. Then it started to go to black and then back on. When I came to some tutorials with no video, I unplugged my headphones to just read the screens and then the screen immediately went black and came back on.
Long story short.....I unplugged the headphones and rebooted the computer. It has been flawless since. Could it really be that simple? The flickers have something to do with the headphone jack? Has anyone else noticed this connection too?? Or should I try to replace my computer? These are old crappy headphones to boot - I will gladly buy new headphones no problem. I hate to replace the computer.
I have already checked the notice on the graphics card firmware update - and it is already installed on my computer. Thanks for any suggestions or help.

I am experiencing similar issues with my new 27" i5. I have not seen the screen go black yet, but there are obvious flickers from time to time. I only notice the problem during/after watching videos (and yes, I have the headphones plugged in). The videos are from Netflix, so I am using the Mac version of Silverlight.
This iMac was purchased because the graphics chip on my 15" MBP started acting up a couple weeks ago and then finally failed completely. Interestingly, I was also watching videos on Netflix with that system when the problems began.
When I first got this iMac the Apple Software Updates downloaded and installed the graphics firmware update. I had hoped that would eleminate the possibility of screen flicker, but it seems that was wishful thinking.
I am going to call Apple tomorrow and see what they say. Based on what I'm reading here I'm not too happy right now. It sounds like this problem is relatively widespread.

IPhone 5 Distorted Video Recording and Screen Flicker

Love most of the new iPhone 5 features and the speed on LTE service is amazing. However, my brand new iPhone 5 64GB seems to be having some issues. Two main issues.
One is an occasional screen flicker consisting of 3 to 5 horizontal black or dark colored lines. This is located at a point approximately 1/3 of the screen up from the bottom and running from the left edge of the screen to approximately the center of the screen. The flickering lines are brief and occassional, but deffinately a concern.
The other main issue is with video recording. I've attended a couple of concerts/shows in the last week. I used my iPhone 5 to capture a few video clips to share w/ friends etc. The recorded videos have brief moments of light to moderate, easily visible video distortion. There's a horizontal distorted digital shaking running the full video width, approximately 1/4-1/3 of the screem and mostly in the center of the video image. It's not related to playback on the sceen itself, but it is the quality of the video recorded. I downloaded the videos to my computer and they play with the same video distortion as they do on the phone. I had previously been impressed with the video qaulity on my 4S. Perhaps issues with over active "improved video stabilization"? Aside from those things all else seems to be good minus some occassional delayed touch responses and seemingly delayed photo opening to view from text messaging.
Hardware? Software? Bottome line, are these issues that may be resolved in a future Apple iPhone 5 / iOS 6 update or must I get back in line and try to get a new replacemnt phone?

This is not an answer, this is just an additional voice to prove and to make it apperant to Apple that they have to do something about all the problems with the iPhone5. I have as TS encounterd the camera/video destortion apart from my bad reception and battery drain problems.
I bought a 32GB black iPhone5, have already changed it once, because of the battery drain, from 100% to 70% during a night, in stand-by mode(no usage).
This second one, still doesent live up to my excpectations, batterywise my 3,5 years old iPhone 3GS is at pair with my brand new iPhone5, video distortion when recording.
I am going to change it today!! third time's a charm... Lets hope so...
