OSX Lion, Graphic Artifacts

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?

Yes - I'm stuck at that moment with a an enlarged Trial FCPX Timeline that won't accept anything. The rest of the prog is apparently operating okay - (imported and appeared in Event Libarary) so I'm waiting on a discussion with Apple's Support in just over an hour's time. Haven't found any of the previous unexpected stuff so I'm hoping it's going to be fixed.

Yes. Transferred my Trial FCPX across to another iMac under guidance of Apple Support then deleted the 27's content and reinstalled 10.7.2 Lion. First internet page I entered almost immediately swept to the right-hand corner with enlarged lettering and I chose View - Actual Size to rectify. Have yet to migrate the FCPX prog back to this 27" iMac. It's at present on a 21.5" iMac with Snow Leopard - but its the wife's computer really and already there's a reluctance to "have all that bother!"


I've been advised that the computer may have to be handed into a Mac shop for repair . . .

Being stuck with an inabillity to gain access to the Timeline in FCPX Trial version, I needed to have it re-installed. That's now done and working perfectly so far, having moved it over from the smaller iMac to my 27" one, I now have the task of removing the contents of my wife's computer from my 27" iMac which I had copied over and would appreciate anyone giving me A to Z insructions on how before I make some sort of ****-up . . . !


I have to say that it does seem to be Lion with the problems and not Snow Leopard.

These problems only started for my AFTER upgrading to 10.7.2. I just reformatted and reset PRAM and they are still happening. When I restart, everything is fine. But after I start using FCPX for a minute or two, the flickrs / blockiness start happening. Then Finder becomes unusable. All of the text turns to little black blocks.


- 27" iMac i7 2009 model

- fresh Lion 10.7.2 install

- seems to be triggered by either FCPX or using my FireWire800 drive

I have got the artifacts going around my screen as well since I upgraded to Lion 10.7.1. Once I upgraded to Lion 10.7.2, the artifacts gone. However, I still had the artifacts, and similar problems, like freezes, when playing video games or when using applications which demand too much from the video card, so I started looking at the video card and found that it was diying. I have like 5 days using the Mac Pro in safe mode because of this.


I would recommend you booting by using other OSX, like for example, Snow Leopard and see what happens in order to troubleshot if it's the video card or the OSX. If you have a Bootcamp partition, you can try there are as well and of course, running a video game. Another good thing, if possible for you, is taking the video card out of your computer and plugging it into a PC Windows and see what happens, even with video games. It's very possible that the problem is in the video card instead the OSX.


As a side note, my video card died since Lion.
