Hello,
I have a HP Media Center computer with a Radeon 9200 video card. After
playing Deus Ex 2 I quit the game back to Windows XP and I could see
some flickering streaks of garbage appearing on the desktop and under
the mouse cursor. When Windows redraws the screen (you know, when you
can see that it's redrawing the desktop and all the icons) the streaks
are cleaned but start appearing again.
Rebooting didn't fix the problem. When I turned the computer off and
then on again, sometimes it appeared and sometimes not.
I had the Catalyst 4.1 drivers when it happened. I upgraded to 4.2 and
it didn't help. Reducing AGP from 8x to 4x didn't help either. Fast
write has always been disabled by Smartgart.
Disabling Write Combine made it work correctly. But since this is an
integrated system by HP, it's supposed to work the way it came from
the factory. (Although I'm not sure if it came with Write Combine
enabled, hehehe. But it probably did.) I don't want to disable it,
since it reduces frame rate.
Have anyone had a similar problem? Is it memory overheating? It seems
like some bits in the video memory are changed randomly.

PS: Update to this post: This is interesting. Last night I installed
AtiTool and 3DMark2001. AtiTool said it couldn't make persistent
changes to my card's clock since I was using the official Catalyst
drivers. I didn't try to do changes anyway, and I proceeded to do some
tests in 3DMark with Write Combine disabled. Then I enabled Write
Combine, rebooted and ran some more tests in 3DMark, expecting to see
the streaking garbage problem. It didn't happen, either in 3dMark or
on the Windows desktop. Then I played some Deus Ex and didn't see any
problem. It appears to have been fixed by itself.
Can any of you explain what was that???
