[Dri-devel] MGA 32bpp bug?

[<pa...@ik...>]

I'm using XFree86 4.0.2 (debian packages) with g400max and kernel 2.4.0.

http://nrg.joroinen.fi/bug/

In the url above, you can find screenshots of the program when it works,
and when it doesn't. Also the source for the program is included.

That program works well without any problems in 16bpp screenmode.
When I switch to 32bpp, that program doesn't work (screenshot) every 15th
time I run it!

The bug is related to clearing the depth-buffer. If I remove the the
clearing of the depth buffer, it works OK.

The program is very simple, it just draws a triangle strip of two
triangles mapping a 256x256 (32bpp) texture to them.

I can see this bug with other apps too.

Sorry for bothering if it is already fixed in the CVS.

btw. Anyone fixing the bug, that causes the freeze of X when switching a
workspace while running a gl-app? Have to restart X before it starts to
work again.. killing the gl-apps isn't enough, all gl-apps just freeze
(before you restart X).


Thank you.
