Bug ID: 45989
           Summary: The Witcher 3 flickers horribly and has artifacts
           Product: Wine
           Version: 3.18
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Gentoo

See the attached video. Basically, certain areas of the screen (e.g. most of
Geralt, the outside sky, certain interior walls) flicker very badly. Also,
there is a grassy-looking wall in the middle of the room.

I am using a Northern Islands class card, so Vulkan is not supported. I am
using Mesa 18.2.2.

Apologies for the potato quality recording; I'm using sway at the moment and
video recording isn't properly supported. I did try TW3 on X though and it had
the same results.

This is may be a dupe of bug 45946. Please try with Mesa compiled with one of
the patches at https://bugs.freedesktop.org/show_bug.cgi?id=108311.

Also, you can run wine without ARB_query_buffer_object which should work around
the problem (assuming it is the same bug):

MESA_EXTENSION_OVERRIDE=-ARB_query_buffer_object wine ...

I set the environment variable but it appeared to have no visible effect. I
also applied Dave Airlie's patch and didn't set the variable and it also had no
visible effect.

Also, I didn't mention it, but if you look closely, you can see narrow
horizontal dark bars on the screen. The opacity of the bars varies based on
camera direction from transparent to apparently completely black. Also, the
edges of the bars aren't solid, they're kinda pokey (vaguely similar to a
zoomed out audio waveform) and move related to the texture displayed in that
area (e.g. if Geralt is under the bar, they kinda jiggle, but on a non-moving
background like the wall they don't move).
