[Bug 74863] New: [r600g] HyperZ broken on RV770 and CYPRESS (Left 4 Dead 2 trees corruption) bisected!
https://bugs.freedesktop.org/show_bug.cgi?id=74863
Priority: medium 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
Created attachment 93888 --> https://bugs.freedesktop.org/attachment.cgi?id=93888&action=edit 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.

--- Comment #2 from Benjamin Bellec b.bellec@gmail.com --- 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".

--- Comment #3 from Marek Olšák maraeo@gmail.com --- Is this fixed with current Mesa git?
If not, could you please make and upload a trace file using apitrace:

Thanks.

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