It doesn't look good, but before saying that it definitely is a
hardware problem, I would ask for the full output from:
Running the command 'xdpyinfo'
The full contents of the Xserver file (which has all the command line
options that the X server is started with)
Also a few tests should be in order:
if you turn off backing store?
if you change resolution?
if you change color depth?
if you disable the 8bit PseudoColor overlay plane?
Remember that even the dmedia stuff from SGI has bugs in it... perhaps
this is some kind of weirdness that is being tickled that won't be
under slightly different X server configuration.
