So it appears as though people are having various display issues, but I was wondering if anyone has seen this problem in Leopard (see attached image). I've actually been having this issue since 2.x. The screen will start to garble after some amount of usage. Only a VM reboot seems to fix it (sometimes I even need to restart the Parallels application in Mac OS). I'm running Parallels on a Boot Camp partition -- but I didn't see this issue in the sticky. Any solutions?
Try this, optional and should be the last step -reset PRAM (once I met such situation with Boot Camp Windows - in my case it helped out) Install 10.5.4 Install 5608 as described in http://kb.parallels.com/en/4790
