            Bug ID: 74863
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [r600g] HyperZ broken on RV770 and CYPRESS (Left 4
                    Dead 2 trees corruption) bisected!
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: b.bellec@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

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>

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.

 Just as info... can not reproduce it on radeonsi with this apitrace, seems
like r600 only issue :).
