Hi!

I am not too certain since which version of xserver-xorg-video-radeon
the trouble started (currently 1:6.13-2 installed in squeeze) because I
don't run the 3d games that regularly, but it seems to have been a
while, I though only now found the time to report this issue.

When using 3d applications like with warzone2100 or neverball the
graphics display is totally unusable, even in windowed mode. There are
extremely large bit planes all over the screen making anything else
unrecognizable.

Anyone else experiencing this issue? Any cure for it? It is definitely
a regression because it worked before, though I can't really pin it
down. Given some private time constraints I unfortunately can't dig
around too much for going through something like git bisect, but I am
confident that I'm not the only one facing this issue so having some
hints into the right direction on what additional information would be
useful from my part or what I could try would be considered extremely
helpful!

Thanks in advance for any hints,
Rhonda

Maybe this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=26496

It does "work" properly when using KMS, but it's also incredibly slow
and has the drawback of not sleeping and doesn't have back light
support. I've been doing without OpenGL on my Powerbook lately (Gentoo,
not Debian).

If you have suggestions for tracking it down further than the bisect,
I'd be happy to take a look. The only reason why I haven't looked into
it further myself is that it was a big blob of a commit and I don't
really have the time at the moment to figure out what exactly is going on.

Sorry,
-Joe
