Created attachment 609289 [details] lspci Description of problem: I am using Fedora 17 KDE on a Thinkpad T41. I upgraded the kernel from 3.4.4-5.fc17.i686 to 3.5.2-3.fc17.i686. When using this lastest kernel, I have some strange black squares on the screen, triggered by my any mouse click action. Themes I am using:Clearlooks Additional info: I made the white squares you can see in one of the screenshots. I did that for privacy reasons.
