Xorg.0.log

The xmms playlist shows randomly scattered blue points all over the window, instead of the expected blue text. xcompmgr active or not does not make a difference. No framebuffer drivers are active.

After adding

Option "MigrationHeuristic" "greedy"

to the Device Section (as suggested by stillunknown on #nouveau) fixes the playlist window, but now all other windows show artifacts.

This is on

Linux darc 2.6.27 #3 SMP PREEMPT Tue Dec 23 12:12:22 CET 2008 x86_64 GNU/Linux

with

01:00.0 VGA compatible controller: nVidia Corporation GeForce 8600M GS (rev a1)

I will add xorg.conf and dmesg in response to this.
