When windows move around (when the user draggs them or when they are created) traces are left over in the root desktop window (nautilus) -> screenshot This using Mike A. Harris experimental monolithic packages on x86_64 fedora devel + Radeon X700 PCIE This is my main home system that is dedicated to Linux so I'm ready to provide as many testing as needed to get it working. The mobo + cpu + gfx card was just replaced after an harware problem.

Does the problem still occur if you disable acceleration (noaccel option)? Also are you using EXA or XAA? If you are using XAA, try disabling specific XAA accel routines (see the xorg.cong man page for how to do this).
The xorg log says its XAA : II) RADEON(0): [drm] drmOpen failed (EE) RADEON(0): [dri] DRIScreenInit failed. Disabling DRI.

In noaccel mode there are no artifacts but the thing is slow as a snail
I can't reproduce the problem with XaaNoOffscreenPixmaps
