I've created /usr/share/X11/xorg.conf.d/15-debugwait-hack.conf 
containing that snippet.

The log shows:

[    57.316] (==) intel(0): Depth 24, (--) framebuffer bpp 32
[    57.316] (==) intel(0): RGB weight 888
[    57.316] (==) intel(0): Default visual is TrueColor
[    57.316] (**) intel(0): Option "DebugWait" "true"
[    57.316] (II) intel(0): Integrated Graphics Chipset: Intel(R) 945GM
[    57.316] (--) intel(0): Chipset: "945GM"
[    57.316] (**) intel(0): Relaxed fencing disabled
[    57.316] (**) intel(0): Wait on SwapBuffers? enabled
[    57.316] (**) intel(0): Triple buffering? enabled


It'll take a while to see whether that makes the problem go away.

I'll send a message the moment I see the problem again, or in a few days 
if it seems fixed.
