            Bug ID: 110370
           Summary: Rendering artifacts in Enter The Gungeon on Both RX
                    590 and Radeon 7
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: Sonicadvance1@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

I have rendering artifacts in Enter the Gungeon with RadeonSI.
Bug was reproduced on both a Radeon 7 and an RX590 using Mesa git versions
The game rendering is fairly simple and may not be too hard to track down.
The rendering artifact is the shimmering around texture edges in the video I
will provide.
I've also attached a renderdoc capture of a frame in the game where the
artifacting is occurring.

Additionally the game is running very slowly due to massive amounts of futex
usages, but I can trace back if those are coming game side or driver side.

Some additional information.
If you change their lighting model from High to Low in the video settings then
the corruption goes away, but this is obviously less than ideal.
Definitely something to do with that shading pass though.

I don't seem to suffer with poor performance even on an obsolete Phenom II x4
955. But now that you've mentioned when I notice a very slight bit of this
shimmering effect on my R9 285, admittedly not to the same degree as you.
It's quite noticeable on the first red step at the beginning of the game and
seems to shift around with the position of the game camera:

Using the GOG v2.1.5 release on:
> Debian Testing
> Linux-drm-fixes-5.1
> Mesa 19.1.0-devel (git-53f715fafb)
> Device: AMD Radeon R9 200 Series (TONGA, DRM 3.30.0, 5.1.0-rc1+, LLVM 8.0.0)
Recorded a trace running the x86 & x86_64 build of the game:
