Created attachment 39619 [details] chckerboard effect in nexuiz In nexuiz and in this webgl demo: https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/demos/google/particles/index.html , there is a checkerboard effect (not black and white, but black and alpha) which should not be there (see attached screenshot) In the webgl demo, the checkerboard effect is in the black smoke (screencast attached). I am using the r300g driver from xorg-edgers ppa with my R350 radeon card.

In nexuiz, the distortion and squares only appear when the "real dynamic lighting" setting is turned on (under settings / effects).
(In reply to comment #2) > In nexuiz, the distortion and squares only appear when the "real dynamic > lighting" setting is turned on (under settings / effects). Can you run nexuiz with RADEON_DEBUG=fp,vp,pstat with and without "real dynamic lighting" and post the output? Also, does running with RADEON_NO_TCL=1 help?

I posted the logs, with and without The problem is especially visible when I shoot with gun number 1 I clicked on single player, level 2 and selected gun 1 and shot a few times. With "realtime dynamic lighting" the checkerboard effect occurs. (the 'with' log) With "flash blend approximation" there is no problem. (the 'without' log) The RADEON_NO_TCL=1 setting caused a problem, I saw distorted pixels on the whole screen and heard the music, so i was unable to do anything.

Today I updated from xorg edgers ppa and the bug in Nexuiz is fixed! Maybe this patch fixed it? http://cgit.freedesktop.org/mesa/mesa/commit/?id=daffaca53e47faeaaefb98ca46fe4870133d9f02
Most probably, yes.
