I think we will have this issue sorted out with 10.7.1 upgrade.

Good to hear that @seukundek ! we'll just have to wait, since 4 days ago this problem didnt show.

I just want to add that it happened again today.

iMac 27", 3.1 i5, 4 Gig DDR3, AMD Radeon 6970M 1024

On iMac Display - Distorted characters in Finder when scrolling.

I do have a 23" cinema display, but not currently connected.

took 2 mins to Fix this easily,

Just Log Out and In and It's Fix.

Just wanted to chime in and say I'm having the exact same issues. Apps look fine, but system wide things (menu bars, drop shadows on windows, dashboard widgets, icons) get that weird pixely look.

Not 100% sure if this is the cause, but it seems to be corresponding to happen after I watch an online video in fullscreen mode.

I also just wanted to see if anyone else here was also having the freezing after playing video bug as well, since that seems to be common with 2011 iMacs. I've had both happen. Didn't have any issues with Snow Leopard with same exact spec'd machine (27" i7, 2GB graphics card). I also have issues with graphical glitches while exporting movies from FCPX. Seems like it could be an incompatibility glitch with Lion and the card.

Hopefully will be fixed with 10.7.1.

I'm also having that problem playing videos and it freeze once , another issue when copying files to external hard drive it freeze but the files already transfered, You can't restart I still have to hold the power to remove the freezing copying files 😟

Hi!

This seems to be a display driver issue. My old iMac24 2007 4Gb RAM 2T drive is just fine with no graphical clitches on screen and no hanging at all with Lion.

My new iMac Core i5 Radeon HD 6970 1GB, 12GB of RAM is getting grazy with Lion. I used it 2-weeks before installing Lion with no issues at all but now with Lion 2-times / day display freezes and only mouse is working and only way to boot the Lion again is to hit the power button.

Typically this happening when:

• Trying to play movies with QuikcTime
• Using Safari having with Flash animation. Yes I have installed the latest Flash plugin but does solve the problem...
• FCP X is freezing so many times that I cannot even remember. (This is really SW full of bugs...)
• Finder is showing graphical clitches on screen frequently

So I spent almost 2500€ for SW+HW and now I cannot do Video editing which was my target... I must say that I'm up set...

Hope that Apple is resolving these problems soon...

I am also having similiar issues, 27" iMac, Lion, 3.4ghz, 12 gb ram, 2gb gfx.
Crazy pixelation in the windows shadows sometimes, sometimes weird artifacts show up on the desktop.

Restarting fixes it temporarily.

Resetting the PRAM doesn't help.

Called apple care, they said reinstall Lion. Also didn't help.

Haven't figured out how to force it to happen, so I don't want to take it to the apple store or they wont believe me.

Anybody fix this yet?

I too had a graphical issue after installing Lion on a 2011 iMac 27-inch, Mid 2011 3.4 GHz Intel Core i7 16 GB 1333 MHz DDR3 AMD Radeon HD 6970M 2048 MB Mac OS X Lion 10.7 (11A511)

It happened after I shut down the computer after install and rebooted a few days later. Dock was jittery, windows opened slowly and when using launch pad.. all the icons were slicing in half horizontally when trying to swipe to the next set.

I did a permissions repair and followed that with a Verify disk. It was the "Verify Disk" that crashed my system. After I rebooted, everything was operating normally. I rechecked the permissions and found most permissions were repaired. I verified the disk and it responded as "OK" (SSD hard drive). I have not had an issue since.

I took note of the permissions I thought might be reponsible.. although I am not sure. Here they are:

Permissions differ on “usr/share/devicemgr/frontend/admin/nl.lproj/app/javascript.js”; should be lrwxrwxrwx ; they are lrwxr-xr-x .

There were other repairs but related to Epson scanners and ARD.

For whatever it's worth, add me to the list of folks with a 2011 27" iMac with the i7 and upgraded GPU that's experiencing these graphic distortions. I'm fairly confident that it's a "Lion 1.0" issue, and will be patched in an update to either the core OS or as a standalone GPU update. Here's hoping...

The Lion 10.7.1 update did no good; it happened again today. Bars all over certain objects. @Macanada I have an Epson WorkForce all-in-one. Does anybody else who's experiencing the issue have Epson scanners also?

Update: Ever since I did a repair disk permissions, followed by a "verify disk", I have not experienced any more graphical anomalies. I just did a repair disk permissions again and the only thing that listed were ARD corrections. I too have installed the 10.7.1 update and my iMac is purring along with nary a hair ball in sight. (.. sorry, could not resist the creative narration .. 😉 )

I've updated to 10.7.1, no hangs now.

However, I'm still occasionally experienceing severe graphical glitches mainly after playing Flash video.
