            Bug ID: 99403
           Summary: Graphical glitches in witcher-1 with wine nine and
                    r600g (rv740).
           Product: Mesa
           Version: unspecified

                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600

Very similar (but visually not exactly identical) glitches exists without nine,
but there are workaround in wine:
[HKEY_CURRENT_USER\Software\Wine\Direct3D]
CheckFloatConstants="enabled"
which helps with it. This key does not make a difference with nine.
There are no such problem with nouveau (750ti) here, os ubuntu-16.04 with oibaf
and commendsarnex ppa.

Experienced the same problem on stock mesa from
https://launchpad.net/~inferrna/+archive/ubuntu/featured-mesa/ (nine enabled)
and wine from commendsarnex ppa.

Could you try the patch from this bugreport :
 https://bugs.freedesktop.org/show_bug.cgi?id=94459

If the bug is still present, please make an d3d9 apitrace of the game that
shows the bug. The smaller the file the better. Upload it on the Ixit Nine ftp
or some filesharing service (like google drive).

Tested on llvmpipe and nvc0 (card NVD9): The bug isn't visible.
Tested on radeonsi (card AMD TAHITI): The bug is visible.

csmt_force makes no difference.

Mark as AMD bug.

Tested with mesa 17.3.0.

Glitches disappeared for me after graphics card upgrade to radeon 560. It very
possible means that amdgpu driver is not affected by this problem.

It's not driver specific bug.

I should have followed the hint that there is a registry entry to workaround
this problem with wined3d. It turns out that this registry entry is
specifically for this bug. The analysis and possible solutions could be found
here:

https://bugs.winehq.org/show_bug.cgi?id=34052#c42


Also, this bug is also tracked at:

This patch seems to fix rendering on Evergreen:
https://bugs.freedesktop.org/page.cgi?id=splinter.html&bug=91808&attachment=139438

Now, it remains to find out why it is reproducible on Tahiti.

If it works OK for you, you are free to close it.
You may also mark it as duplicate of
https://bugs.freedesktop.org/show_bug.cgi?id=91808
Since both issues seems to be fixed by same change.

About the problem still existing on Tahiti, the issue might be some other
(similar) bug. I've been told that you can't just port that fix to radeonsi/gcn
as they work differently.

But it is not problem to open a new issue for it.
