Description Cyrill Helg 2006-11-05 03:10:44 UTC
I'm using the impressing r300 driver on my Radeon X300. Everything seems to 
work fine except one small thing:

Parts of the screen sometimes don't get refreshed corectly. I will try to 
explain by an example: I'm scrolling in firefox and then a popu shows up 
(from kopete - a kde instant messenger - for example) The content scrolled 
behind that popup stays as it was or looks very funny. See the attached 
screenshot.
I'm not sure if we could characterise the problem like this: Whenever a window 
or a change on screen appears which was not caused by a users click or so 
strange thing happens. I'm encountering the same problem while chatting with 
kopete: The chat window with the messages in it gets black sometimes, but 
then switching tabs or minimize, maximize causes a manual refresh and its 
fine again....


I hope you understand me. =)

Thanks a lot for your help.

PS: I experienced similar effects on my friends laptop on a fireGL ati card, so
it's not hardware related in my opinion...

Do you experience the same problem with DRI disabled ? Are you using
a compositor like compiz or beryl ? Could you try with AIGLX off and
dri off in your xorg config.
Comment 3 Cyrill Helg 2006-11-05 05:09:55 UTC
Hmm strange I can't reproduce the problem at the moment. I'm using aiglx, but I
can't use beryl because the scrolling is very slow, see the ticket here [1] if
you are interested, probably you know a solution for that. The interesting thing
is that they say it's a bug in compositing/mesa.

I will come back to that when new xorg/mesa is out and working here. (The
current 1.1.99.901 version from gentoo crash my system when terminating the
X-server)

If you're using XAA, you need Option "XaaNoOffscreenPixmaps".
Comment 5 Michel Dänzer 2008-04-09 00:32:37 UTC
Assuming this is related to comment #4. Please don't reopen without at least attaching full xorg.conf and Xorg.0.log.
