Which Linux Graphics Driver Bugs Do You Hate?

What gets me is what people are using to set the bar for drivers.
Compiz: experimental software known to break shit. My shit is broken, NVidia and ATI need to get their act to geather?
KDE4: Known to underperform its predecessor KDE 3.5. KDE 3.5.x works just fine and is lightning fast with the same drivers and hardware. KDE4 does not. Therefore, its NVidia's fault?
Same hardware, same distro, same drivers, same game, same settings (everything turned up), desktop effects disabled:
Code:Prey under KDE 3.5.9 3545 frames rendered in 101.2 seconds = 35.0 fps 3545 frames rendered in 101.2 seconds = 35.0 fps 3545 frames rendered in 101.2 seconds = 35.0 fps Prey under KDE 4.2.0 3545 frames rendered in 125.3 seconds = 28.3 fps 3545 frames rendered in 122.4 seconds = 29.0 fps 3545 frames rendered in 122.4 seconds = 29.0 fps
I'm sure Nvidia and ATI could do a lot better but lets be fair. They aren't the only ball players on the field.

Originally posted by Chewi View PostI don't seem to have as many problems with fglrx as most people. The video tearing is annoying but I can live with it until the open driver supports 3D. The one problem that really bugs me is that logging out or trying to restart X in any way sends the card into a spasm. The display freezes, the graphics fan starts going full pelt and the only thing I can do is hit the power button, which at least shuts down the machine cleanly. If it was a hard lockup then the file corruption probably would have made me chuck my card by now.

Bug is still not resolved, but there is a workaround which fixed my problem.

If KDE 4.5 starts preforming better than 4.2 on the same drivers and hardware then what... you'll eat your socks?

Originally posted by Saist View PostIt's of little surprise to me then that I run into installation problems with Debian (Pure) based distributions when the maintainer of the packages or scripts is working on a deliberate fork.
Now, maybe the Debian problems could be solved if Ubuntu developers focused on maintaining Debian compatibility.
However, I'm not sure bringing what amounts to be political and personal issues into a discussion involving whether or not an installed driver functions as expected in an installed enviroment.
I really can't comment on the Ubuntu (not) maintaining Debian compatibility other than I'd like this doesn't stay our problem in future...
Everybody, sorry to get little OT...

Originally posted by oblivious_maximus View PostThe 180.xx drivers were a lot faster with KDE4 than the 177s and earlier versions, but it was still a pretty slow experience trying to use KDE4 with my 8600GT. I'm sure KDE4(and/or its dependencies) is partly to blame, but Nvidia's blob surely is also.
QT 4.5 is much, much faster IMO. Might be interesting to see some benchmarks there, Michael.
