MacBookAir screen flashes when waking up

I have a mid 2011 MacBookAir.
Since getting the Mountain Lion the screen has almost constanly flashed when I open the cover to wake the computer from sleep.
It's like PhotoBooth flash, but there isno picture in photobooth.
What is this? Should I be worried?

I'm having this issue as well. It appears that 2012 Macbook Air users are too:

Hopefully we get an update soon that fixes the issue.

Screen flashes when waking up from sleep, Macbook Pro Retina 13" early 2013

Hey guys,
I have an issue with the wake up procedure on my new Macbook Pro Retina 13". This is how it looks: http://youtu.be/pBK8vRiVdX4
When my computer has been in sleep mode for a longer time (approximately 1-3 hours) it does this strange thing when I open the lid. It is black for a time and suddenly there is a blue flashing screen before it goes to the desktop. This process is about 10 seconds.
Does anyone know if there is a solution for this? Have you had the same problem? I called Apple support this morning and he told me to reset SMC and clear the PRAM, but the issue is still there.
Please let me know if you know something about this.
Kindly,
Mikael

i had the same problem too and i think i could isolate its cause. I tried a few things on my 13 inch retina macbook pro like switching off functions like ''put hard disk to sleep when possible'' but this wasnt a solution to the problem... after alot of playing around with my macbook, i realised that this flashing problem only occured when my macbook was scaled up to any resolution other than the native resolution... when i went back to the native resolution, the flashing stopped and my macbook started almost instantaneously after opening the screen... you should try it out... and tell me what you think...
think it is pretty annoying that we get this issue when scaled up to some other resolution and wish there is a solution somewhere online to solve this... but for now, i think it is quite an annoying bug but still not something i cant live with...
tell me what think about it:)

Screen flashes when using selection tool in Photoshop CC

Does anyone know why my Windows PC screen flashes when I try to use the selection tools in Photoshop CC?

Hi - thanks for your comments. It was happening on all of the selection tools however I have solved the problem by changing the 'Advanced Graphics Processor Setting' to 'Basic' in Photoshop CC.
Thanks anyway

My iphone5 screen flashes when trying to make a call. I can't access any of screen features.

My screen flashes when trying to make an outgoing call. I am unable to access any of the screen features such as keyboard etc.

Could be a problem with the proximity sensor. Are you using a case around your phone or a protective film attached to the screen? If yes, remove them, to make sure that the sensor is not covered.
Also try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose data by resetting.

Screen issues when waking up from sleep

Very strange things going on with the screen on my new MBP, it has only occurred on a very few occasions now, after waking up from sleep. I noticed two strange effects happening, not at the same time so I don't know if they are related or not.
1) Sometimes the screen shows a varying brightness pattern at the bottom, I think caused by some of the LEDs from the backlighting having a different brightness then others.
2) Sometimes the entire screen has a blueish hue.
Both issues are fixed when I restart the computer.... anyone know what might be going on...?

Also when it wakes up from sleep the screen flashes, don't think its supposed to do that.
Here is a picture I took with my phones that shows how the screen looks like, notice the difference in brightness in a pattern.

White screen flash when I use Preview to look at pics!

GDay all
About a week ago my G5 Duel started flashing a white screen (like a camera flash) when I load any jpg tiff or pdf using Preview. I minimise the photo file, then load it back to full size and I get a white flash.
Its like someone is taking a screen dump of my screen every time I use the preview program... If I was on a PC I would think I was being hacked...
Any ideas?

Create a new account, name it "test" and see how your apps work in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
Open System Preferences >> Accounts >> "+" make it an admin account.
If the problem is present in the test account also, then it is systemwide. In this case try repairing this with the 10.5.2 Combo Update This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
If the problem does not appear in the test account try starting in "Safe Mode" (It will take a bit more time to startup because it runs a directory check first).
If that works go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If there are still problems, go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving /Users/Home)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
Let us know.

My thunderbolt screen flashes when hooked up to macbook pro after downloading new lion software

does anyones monitor flash when using new lion software and thunderbolt monitor

You have the display set in Extended Desktop mode with the MacBook as the main screen. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.

Screen Flashes when opening lid after locked - T410s w/discrete -- Video of problem inside

My computer is set to password lock (in Windows 7) when I close the lid, but remain powered on. When I open the lid of the computer, the screen flashes around 10 times before it gives me the login screen.
My bios is updated, my graphics are turned to 'high performance' ... always on - when plugged in with A/C adapter.
Anyone know what the problem might be?

@paradiddle,
If it is possible, could you try removing the password so when the system wakes up from sleep, see if the screen flashes.
Also when your display is "out" to the TV via HDMI, try pressing Fn + F7 and see if you are able to switch it back to laptop view without rebooting. You could also change this via Display Properties.

White screen flash when shutting down after a suspend

If I have suspended my laptop at any time during its uptime, when shutting down the screen flashes white, but it turns off as usual. This only happens if I have suspened.
There are no issues as far as I can tell, I see nothing much in journalctl when comparing a suspeded shutdown vs no suspend.
Im using nouveau, and I'm up-to-date as of now.
Google hasnt returned much,
Anyone else seeing this?

Screen flashing when I try to open an app.

My screen just flashes when I try to open a couple apps that have always worked fine before.

First thing to try is a reboot of your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.
If that doesn't work try downloading any free app. Then reboot your iPad and delete the downloaded free app.

How to avoid screen flash when access many cells in matrix?

Hi,
I need to do some automation in the matrix, I need access some cells one by one and assign value to some cells too. When this action only touch 1-2 cells, then the screen flash is acceptable, but if too many cells touched like more than 5, then the matrix flashing become pretty ugly. My question is can this flash be avoided?
Thanks!

Screen "flash" when navigating

This is a wierd one. I published my first site today (DWCS4). Everything went fine, all the links work, pages look like they should.
The problem: Only in IE, when I navigate between pages, before the page appears, I get a quick bright flash (almost like a camera flash) and then the page loads. The flash only lasts about 1ms -- very quick. This does not happen with Firefox, Safari or Opera.
It's really annoying, so if anyone has a fix, I'd really appreciate it.
Thanks,
Tom

CS3 exporting drop outs and red screen flashes when exporting via Media Encoder

Hi forum
I have been using Premiere Pro CS3 for a long time on my dual core PC with no issues. Suddenly, I am now getting a major issue i MUST get sorted asap for a client is waiting for the final video.
It is a HDV (1080i, 25fps) project/timeline. An 8 minute video has been put together in this and every time I try to export as either MPEG2 (Blu Ray) or WMV, I am getting pixelation in certain places usually around certain cuts, or horrible red blocky pixels filling up the screen for a second or two. They seem to come always at the same point. They don't happen when i render the timeline or show up when playing the edit itself in the timeline - just when i playback the exported video in premiere or in Windows Media Player.
To try a workaround I exported the whole video as high quality MPEG2 (blu ray - 30mbps), which I brought into a new sequence, then I exported small sections where this problem was happening as Uncompressed Microsoft AVI and called them "patch 1", "patch 2" etc. and brought them back in and overlayed over where the problems were occuring. The short Uncompressed AVI patches seem to have exported with no glitches, so theoretically I thought I had a clean good timeline in my new sequence made up of the MPEG 2 video overlayed in the dodgy places with uncompressed AVI "patches". However, trying to export a new MPEG 2 master from this has created the same problems, in the same places!!! Still drop outs and still those horrid red flashes filling the screen. Not always as bad, and some places where there were problems are ok, but I am still left with most of the problems still there.
I am now trying to export the whole video as an AVI uncompessed but dont know if this will work and will take a very long time.
I do have Saphire plugins, but they are not being used in this new sequence so therefore could that be a possible problem? I thought perhaps it was the brightness/contrast filter etc so removed that from some of the problem areas, and it helped on some of them, but not on others, so not sure its anything to do with my plug in or filters.
Any help would be greatly appreciated.
thanks, James

This topic is about a year old, but I thought I would reply because I just experienced this problem very recently and stumbled upon an easy solution.
Problem: When using Adobe Media Encoder to create an HD or .m2v video file, a bright red screen will flash followed by a mashup of red blocks/pixels somewhere within the file you've just encoded. This phenomenon lasts for exactly 10 frames before clearing up. Most likely, you won't see this problem until you import the encoded file into Adobe Encore. It shows up on the timeline, the preview monitor and the DVD itself. It occurs on edits that the system reads as being corrupt or when a flash bulb goes off from a still camera. Both instances make the encoding process go haywire.
Solution: Encode your HD or .m2v file with CBR (1-pass) bitrate encoding rather than VBR (2-pass). Don't worry about losing any quality in your video or creating unnecessarily large file sizes with your new renders. I guarantee you won't see much of a difference, if any. I can't explain why this solution works. It just does.
Hope this helps you as much as it did me.
