Xorg.0.log at 564e4a98
Anyway, the final Xorg.0.log.
But: Commit "sna/gen2+: Replace composite sources with solids where possible"
causes the xserver to instantly crash when starting certain programs (noticed
it with Chromium, pinta, and gimp):
Program received signal SIGSEGV, Segmentation fault.

BT was taken at git-head, ie. "Move constants MOCS", then I "bisected" to find
which of the three new commits was the cause.</pre>
