It might be this bug:

http://www.winischhofer.net/linuxsisvga.shtml

(scroll down or search for 'XFree86 XAA library patch (Recommended)')

I quote:

		I discovered a bug in the X server's XAA code (outside the SiS driver),
		which has been there since before 4.1 - and was never detected until
		recently. This bug is now more often triggered by the RENDER
		acceleration, but might show up even without it, for example, after
		heavy Xv usage. Download the archive for your version of XFree below,
		extract the archive and copy the file libxaa.a over the old one in
		/usr/X11R6/lib/modules. Don't forget to do that again everytime you
		update your X packages! Debian users: Debian's 4.2.1-12 and
		4.3.0-pre1v3 versions do not require this patch, previous versions do.

This sounds like the behavior that you described.
