Bad rendering screen 1
Since mesa-9.0, light is rendered incorrectly in the Penumbra games (Overture,
Black Plague, Requiem). I find it hard to describe so I've included two good
and two bad screenshots from two scenes to illustrate the problem. For, fixing
this bug would mean rendering of light sources as in the "good" screenshots.
I've bisected (between mesa-8.0 and mesa-9.0) and the first bad commit is
134a0a5ff88851c971fb95863317f640b5b9fa3a , r300/compiler: Use the smart
scheduler for r300 cards. I then checked out current master and reverting this
commit fixes the problem in master.
I compiled mesa with the following options:
--with-dri-drivers="radeon,swrast"
--with-gallium-drivers="r300,swrast"
--enable-gallium-llvm
--enable-texture-float
--enable-gallium-g3dvl
--enable-glx-tls
--enable-motif
--enable-xvmc
My system is Slackware 14.0 with kernel 3.7.6, libdrm-2.4.42 and
xf86-video-ati-7.1.0.
