Q: OSX Lion, Graphic Artifacts

There's an update for Lion available now that supposedly fixes this, so just check out Software Update.

I ran the updater first and the problem was still there.  But apiing teh PRAM and the updater seems to have worked.

new Update + reseting PRAM dont work for me.. It is still there..

Still occurs for me, but I find what randomly triggers it is watching a video (mainly YouTube). Sometimes they run fine, and everything is fine after I've watched one. Other times the video will flicker with green and then UI elements/menus start to mess up.

Well, I have updated to 10.7.1 and problem is still there.

When it happens I just restart the WindowServer process to avoid restarting the whole OS. You can open terminal and type:

sudo killall -HUP WindowServer

and press Enter, but be careful as all the opened programs will quit, though, is still faster than to restart...

Do we even know if Apple has acknowledged the problem yet? I don't need a ETA on getting it fixed. I mean, its apple and they don't do that. But this is a serious problem And I'd like to know it's at least on their to repair radar.

I can confim that 10.7.1 fixed my artifacts problem in finder, I only ever had a problem in finder, which is gone.

s.illes79 > I think if you will try it more times in Finder list view with many items, scroling up and down few times, this problem will occur again... I dont believe it is gone.. try it again and you will see...

I still randomly get the artifacts after updating and resetting PRAM. Well, obviously, because the 10.7.1 changelog doesn't mention this issue as fixed.

The Apple Support page on iMac's, "Troubleshooting issues with video" gives information on pixel anomalies.

Does this fit the problem you have?

No, it isnt fix for us. It is only about pixel anomalies on your screen, but we have software problems no hardware problems. Problems come with new Lion, in Snow Leopard was no problem with this..

I did the update and zapped PRAM, I thought it was gone but seems after a day its back and worse, finder is impossible to work in which makes moving files around difficult. Thinking of downgrading to snow leopard, what is this window vista we're dealing with? I would expect much more from apple. Seems highly restricted to the iMAC though as my MBP is not having any of those problems, although it does seem more sluggish may try a clean install or downgrade that as well....not happy with lion at all.

I note that one thing suggested for screen anomalies, blurring and corruption is reset the SMC

Hi There,

upgrading to 10.7.1 didn't help.

the widgeds are still blurred, the menubar isn't readable and sometimes there is even a new problem the window icons are having a green shade.

i am very disappointed, i just bought the newest and fastest andmost expensive imac and it's just not working...
