This is a known issue with DRI and compositing at the same time. DRI2 resolves this problem, but the radeon driver still has to be updated to it. See http://bugs.freedesktop.org/show_bug.cgi?id=8732 for more information. (In reply to comment #1) > This is a known issue with DRI and compositing at the same time. That might explain the glxgears problem, but there is still the corrupt gnome-panel. E.g. the stack of horizontal lines near the System Monitor displays that should be a Volume Control icon. Mind you, the gnome-panel corruption "went away" once I'd hacked together a SetTexOffset implementation for the R100 driver. As always, please attach the full xorg.conf and Xorg.0.log files. In particular, if you're using Option "AccelDFS", does the panel corruption persist without it? Created attachment 17711 [details]

Desktop corruption when enabling Desktop Effects.
This corruption "goes away" now that the R100 driver accelerates GL_EXT_texture_from_pixmap, but I suspect that it's simply avoiding the problem rather than fixing it.
Does it also happen without Option "AGPMode"? Created attachment 17764 [details]
Xorg log file without AGPMode
Yes, the corruption still happens.

Xorg log file without AGPMode and using XAA
Yes, the corruption still happens when I switch to XAA instead of EXA too!
However, I should point out that the corruption is no longer observable if either I don't start X or I leave the computer turned off. This may or may not be significant.
BTW, why is Firefox complaining about invalid security certificates from bugs.freedesktop.org? I've had to create a scary "exception" to login here.

I've had to create a scary "exception" to login here. Sadly, Mozilla's opinion is that security comes from paying shitloads of money to VeriSign. Hopefully they'll see the sense in publishing the CACert CA, and we'll have a CACert certificate, which will validate. Mass version move, cvs -> git Is this problem still around? According to comments #6 and #9 it is fixed in the currently preferred codepath (KMS/DRI2/EXA). > Sadly, Mozilla's opinion is that security comes from paying shitloads of > money to VeriSign.

See http://blog.thoughtcrime.org/ssl-and-the-future-of-authenticity for more information. I got no response in 3 years, I assume this is either fixed or nobody cares about r100 anymore. |

Created attachment 17650 [details] Desktop corruption when enabling Desktop Effects. I enabled Desktop Effects on Fedora 9, ran glxgears and observed the following effect when dragging the glxgears window around the screen (see attachment). The icons on the gnome-panel at the bottom of the screen were also corrupt. I have a Radeon 7000 AGP card, with a 500 MGHz PIII CPU.
