OSX Lion, Graphic Artifacts

I've been through that procedure twice now, Byron, and although there is s significant improvement first of all, over time there is a settling down to the original problem. I'm UK but got through to the American Support and told them it was a bug and that a very large number of people are reporting it in the Discussions Forum. That bug point was emphatically denied . . . I don't blame Apple too serioiusly on that - provided they recitfy!

I have the same issue, but only when I scroll the finder in a directory that contains a lot of files. Looks similar to other finder screenshots in this thread. I noticed it happened typically when the the scroll bars would appear and disappear, so I tried changing the scroll bar option so they are always displayed. After I did that, the finder issues went away (so far). That would definitely tell me that this is a software issue. Only had this option set for a day, but the moment I changed it and started scrolling up and down rapidly, I could not reproduce the corruption issue in finder, which was consistently reproducable before. Curious if this resolves the issue for other people who have the same finder graphics corruption issue during scrolling with the mouse.

I did all the hoops that Apple Support threw at me with artifacts soon to return. Went back to SL for awhile but missed Lion. Reinstalled Lion with one exception. I did not upgrade to the latest Flash.... Two weeks now @ 24/7 with YouTube galore and no artifacts.

Maybe this removes problems with artifacts when playing YouTube videos, but in my case problems in Finder persist.. 😟 I removed flash from my system, but Finder artifacts are still there. But maybe this is another problem, because I never have problem with artifacts on YouTube or Dashboard.. only in Finder, when I am scrolling.. Removing flash do nothing in this case.. 😟

Since I re-installed Lion (about a week ago) all works okay, however, I cannot play Assassin's Creed 2 for mac. Artifacts appears while playing the game or in the game menu, making the game crash. Because I have a Bootcamp Partition, for games which are not available for mac, I tried running a couple of games over Windows 7 and strangely, games also don't work pretty well too. They crash or similar things, also artifacts and low perfomance and some glitches on the screen as well). Updated to Bootcamp 3.3 and the problem persist.

This seems to lead towards the video card, but strangely, once re-installed Lion, all the video problems dissapeared magically on both OS (except fot the video games, which problem I'm experiencing right now).

Before re-installing Lion, when I started to have this bad experience with artifacts, I had the same problem also when I was in Windows 7. For example, the translucent features of windows where turned off (the Aero thing). When turned on, Windows was unable to start.

So, the videocard is not the problem but something in between, which leads me to the video card drivers. However, each OS uses its own video card driver and just one of them is turned on when the other is turned off, so it cannot be possible a kind of conflict among the drivers... Still wondering...

Ø3 🙂

I hope everyone is doing what I do and gives feedback to Apple. It's the only really sure way of knowing they are 'listening.'

You were right Ron - the artifacts are back, sigh.

I will be phoning Apple Care again today :-(

There is something really weird going with these artifact things... I just handled myself to install a PC SATA CD/DVD Burner in the Mac because I wanted to downgrade to Snow Leopard and I've installed it, but into another disk partition, so I'm now into Lion again and now there are no artifacts on Lion and the system is stable, without freezing 🙂 Such strange thing is going with Lion... I don't know... 😐

However, I still have to try what happens with video games, since the artifacts appears on screen mostly when using the features of the video card and video games do that a lot.

Will come back when having more news...

By the way, how do I send feedback to Apple? I tried a link who someone passed me but didn't work.

Ø3 🙂

I'm not trying to be smart and I'm not much of a computer guy (but I'm trying to learn). The one thing that I have learned is that you never download software, updates or apps when they first come out. PC, Mac or smart phone. They always have to have time to work out the bugs. Also there can be compatibility issue that you might overlook. Take the lion upgrade, I was thinking hard about downloading it the other day when I stumbled across information that told me that my Rosette Stone software won't work with this OS. That's a 500 software package that I would not have been able to use. Point is, let others figure out the bugs. Hope this helps for next time.

I actually don't blame Apple for ditching Rosetta. Developers had 10 years to transition to Cocoa. And when the most of them started to do that? A year ago at best. But most of them -- only after the Lion release. And now users have all kinds of bugged software.

As for the Lion, I have to agree. I didn't expect it to be so bugged. I've always been upgrading Mac OS X the day a new version comes out and never have I had any problems. Until Lion.

I've been running all kinds of heavy OpenGL games since Lion: Starcraft 2, WoW, Assassin's Creed 2, Portal 2 (what's with all the two-s?) and didn't get any artifacts. But playing video files on and off fullscreen mode -- almost right away.

Yeah, I have red that all these issues have been experimented by the Lion users. I haven't had any artifacts when playing video, just today in youtube, for example, but I had all the others problems. Also, when using Photoshop with OpenGL features activated as well. It seems that the problems starts randomly and finally, it shows in any thing made into the computer that involves the use of the video card. I also had experienced these buggy things, but in other manner, not with artifacts, in my bootcamp partition too.

I have exactly same problem. on my iMac 27 mid-2011 w 6970 1Gb. I own this mac for 3 weeks, and I encountered this problem twice. Artifacts disapear after restart.

In bootcamp win 7 64 I didnt noticed these glitches. But Im waiting for RAGE to play, and probably meet ones )

Rosetta Stone and Rosetta are 2 different things. The language learning application, Rosetta Stone, has most-likely been updated to be a Universal Application, and will run fine on an Intel Mac.

The Rosetta that has been removed from Lion is a translation layer in the operating system that allows software compiled for the Big-Endian PPC Architecture to run on the Little-Endian Intel Architecture. While it may suck for some who still have software that hasn't been updated, it's been about 5 years now, and viable alternatives may exist.

That said, I am having the same artifact issues on a Mid-2011 i7 Core IMac 27 with the Radeon 6970M 2GB video card. I'm glad to see it isn't just my hardware. Will be calling AppleCare in a minute to report it.

Downloading 10.7.2 NOW ... 4 hours to go ... 888 MB ... it's better fixes these artifacts 🙂
