Hello, after i've installed OSX Lion on my iMac 2011 27°, i started getting strange graphical artifacts on my desktop as you can see in this screenshot. http://t.co/5EXmRfL
The graphic artifacts randomly appears, without that i am doing nothing in particular.
Is this a common issue? It's a Lion issue (fixable with an update) or should i format my iMac?
iMac, Mac OS X (10.7)
Oh man!!! Thanks so much for this great info!!! This is The Evangelium Update!!! 😀
anyone that test new version know if the artifact problem was solved?
I'm on 4 minutes to know that 😀
So far, so good...
Well... I went straight to the point and executed Assassin's Creed 2. Artifacts still there and the Mac crashed... 😐
after 1-2 hours of use no sign of any artifacts in finder
Using it for 2 hours. The artifacts are gone! 🙂
updated to 10.7.2 (11C74) via software update to 1 of my machines, a MBP 3,1. Now any apps with scrollbar has this problem!
I don't know if it was such a casuality or what, but since I got the artifacts going mad all around the screen, my video card experimented a failure (that's why still seeing artifacts in video games). I plugged the video card into a Windows PC and I got the artifacts when gaming. Somehow, the fan of the video card isn't responding as it should when gaming.
Okay, it seems this thread died with the artifacts 😀
Are you saying you somehow took the graphics card out of an iMac and put it in a PC machine?
nooooo! From a MacPro 😀
Another 'phone call to Apple Support tomorrow. Still get sudden pixel count changing which produces a swift shift to one corner of the page and much larger lettering etc. Jerking pages. Now, no active Timeline in FCPX. Stuck.
I'm sure my video card was screwed by these artifacts going on Lion. At least, I know my video card is screwed so far. If possible for you, take out the video card and install it on a Windows PC and see what happens (playing a video game will let you know). I think usign just Bootcamp to troubleshot the video card should be enough, but the latest of the latests proofs is running the video card out of the system that it belongs to.
i test for one day.... nothing artifacting appear..... i hope was solved.... quantum your problem maybe become a hardware problem after your training test fors solve the problem??
Yes, right now is a hardware problem, but this happened after the artifacts. I mean, when having the artifacts, I was able to play video games, which wouldn't be possible if it would been a hardware problem. Later it become a hardware problem 😟 Anyway, I have many months on thinking on buying a new video card. My video card still functioning, but cannot use it for exhausting tasks, such as gaming, due the overheating of the GPU. I know it's not a VRAM problem because of Aperture, which use mostly video RAM (all of it, in fact!) and artifacts did not appear in that circumstance.
Here is an screenshot of how much VRAM was used by Aperture when I just opened (nVidia 8800 GT 512 MB DDR3 [46% used by Aperture] and system RAM is 8 GB [67% mostly used by Aperture and much less by other applications]). Ignore GPUT (temperature). I think aTmonitor doesn't read the GPU temperature (I tried getting a reading when gaming but nothing came out of that):
