Thanks for reporting it.  Sounds like [1] (glyph cache corruption).
Might be related to bug#600474.  It seems to have been introduced
between 2.6.33 and 2.6.34, but since it's an intermittent problem,
bisection is hard.  Putting

	Section "Device"
		Identifier "Intel"
		Driver "intel"
		Option "DebugWait" "true"
	EndSection

in xorg.conf avoids trouble for some people.  The upstream report
contains some kernel and userspace patches that in combination work,
at the cost of some other regressions. :/
