Created attachment 93888 [details] tree correctly rendered Probably the same issue than: https://bugs.freedesktop.org/show_bug.cgi?id=74803 Trees in Left 4 Dead 2 have some rendering issue when you move, so in fact they looks like to blink. See the screenshots attached. This hits my RV770 (HD4850) and CYPRESS (HD5850). When R600_DEBUG=nohyperz is set, there is no problem. R600_DEBUG=nosb doesn't fix. First bad commit is: r600g: defer shader variant selection and depending state updates commit a144bc29b5bb8322a54308603c5d0a8467448164 Signed-off-by: Vadim Girlin <vadimgirlin@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Note that the bug happens in L4D2 only when the option "Effects details" in the graphic options of the game is set to Medium or High, but not when set to Low.

I forgot to mention that I compiled mesa with: ./autogen.sh --with-gallium-drivers=r600 --with-dri-drivers= --enable-texture-float --disable-dri3 --disable-r600-llvm-compiler --disable-gallium-llvm --enable-32-bit CFLAGS="-O2 -m32" CXXFLAGS="-O2 -m32" --libdir=/usr/lib The screenshots have been taken in the level "Dead Center" stage "2 - Street".
Is this fixed with current Mesa git? If not, could you please make and upload a trace file using apitrace: https://github.com/apitrace/apitrace Thanks.
Problem still persists with current master (git-e8f8353). Tested on Evergreen. The apitrace can be downloaded here : https://drive.google.com/file/d/0B7D2Y0QXFND2bUlVc1JyMHZKVWc (364 MB, md5sum 3e80394465612a7f29aced09ea02bd78)

This is also not fixed on RV770.
