Very interestingly, I experience a similar problem under the 4.0.1 X
server with the game X Scavenger (xscavenger). When Scavenger first starts
up, the outer borders of the window are leftover bits of comics that I've
been looking at. When I start the game, though, the screen is cleared and
everything goes to normal.

I've glanced over the source code of X Scavenger, and it appears to be a
problem with the screen-clearing routine. Perhaps an undocumented feature
(i.e., bug) of X 3.3.* that was "fixed" in 4.0.1? I suspect it's a 3.3.*
bug because Scavenger exhibits similar problems when compiled on a Solaris
workstation -- which leads me to suspect that it's relying on an old
(broken) behaviour of the X libraries. If so, then I'd file a bug against
gdm. (But of course, I didn't spend much time to look into this, so I
might be totally off to lunch here.)

I also use a SiS chipset, but it's the 6326 not the 86C326 (or are they
the same thing?). I'm not sure if this problem is chipset-specific, but I
don't know for sure.
