Hi,
I've just tried out the r300 driver - works remarkably well for "untested and
broken" code.
:))
I've run into 2 bugs though:
It doesn't work well if the display uses 16 bpp (24 bpp works perfectly) -- 3D
in 16 bpp is pretty badly misrendered (sample attached; 2D works well w/ r300
DRI even at 16 bpp) -- mixed with a random section of the rest of the screen,
wrong colors, and drawn way too large (but close enough to the expected
output to recognize it).
I don't think we ever focused on getting 16bpp right - having 32bpp
working is fun enough :) Also, all of r300 and later cards have more than
enough RAM for 32bpp modes.
That said, it is probably just a matter of making sure some constants are
set properly (like colorbuffer parameters), I don't think anything else in
the driver is tied to that.
The 2nd bug is that tuxkart (http://tuxkart.sf.net/) segfaults when starting a
game -- apparently the driver is returning a wrong value (or NULL pointer?)
somewhere. The game works on r200 and i855; didn't have the time to do a lot
of debugging yet.
Works fine here - try latest R300 CVS and latest Mesa. I am not playing it
fullscreen if this matters any..

Any ideas?
Thanks,
