Hi,
just experienced the second (partial) crash of my graphics subsystem,
this time I'm able to report it instead of rebooting the machine, as the
remaining functionality is much greater this time...
Yesterday it happened within rssowl, scrolling down to an embedded gif
animation; this time it was just random surfing the web with firefox,
reading news at a hardware magazine. Screen goes blank for a moment,
afterwards characters go invisible or form blocks and special chars,
title bars of windows go black and buttons become unreadable (however,
stay functional). Within an already opened vmware machine, the mouse
pointer is just a rectangular mess of colorful pixels and some milder
screen corruption happens. Restarting applications does not fully
recover the state (but it "cures" over time). Some applications are
affected much stronger than others, rekonq (why do I have to report bugs
with rekonq?!) offers now full functionality, while content in firefox
was nearly unreadable. Will append photos if it occurs next time, as
there are no real artifacts left that would describe the initial
problem.

trimmed xorg log is attached. Maybe you can also spot the reason for a logout
overnight, as I left a locked session running and after returning Kubuntu
wanted me to log in. Firefox and others told me about a program crash, so the
session wasn't exited properly.
