I have added "irqpoll" quirck for the kernel to take IRQ used by USB for mouse and keyboard. Not sure it can be related.

Is this a recent regression in git? If so, can you bisect?

I cannot tell if this is a regression as I got this second hand hardware recently. The original Radeon X300 card worked ok. Only when I swapped it for an HD4350 I started to see those corruptions. I also tried with a friend's HD4350 from another brand and see the same corruption.
I went back to the commit below and still see the corruption. commit f7a91ece264af9f3fd2fc18e99aefcda93ce9f5c Author: Michel Dänzer <daenzer@vmware.com> Date: Mon Jun 14 08:52:16 2010 +0200 Convert x(c)alloc/xfree to m/calloc/free. Fixes deprecation warnings with xserver master and should also work with older xservers. The corruption are visible: 1. on the KDE panel, 2. on the bubbles that show up when cursor is over an icon on the panel or the desktop, 3. on the backgroud when KDE asks for confirmation to logout, 4. on regions of windows that are shown just after beeing scrolled behind the panel. Looks like panel corruption gets replicated on the windows (this is with desktop effects disabled). With Gnome I have observed only problem number 3. Benoit
