--- Comment #24 from Marti Raudsepp <marti at juffo.org> ---
Caught an assertion failure...
Xorg.valgrind: sna.h:514: sna_pixmap_unmap: Assertion `pixmap->devPrivate.ptr
== ((void*)((uintptr_t)(priv->ptr) & ~1))' failed.
(I'm not running in valgrind any more, but I still have the diversion)
I backed up the core file, stderr and Xorg log, let me know if you need any
more info.

Here's something weird... Is this supposed to occur?
