            Bug ID: 102638
           Summary: Incorrect rendering in OpenGL 4 (Unigine Superposition
                    + others)
           Product: Mesa
           Version: 17.1
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mj.wilson.uk@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

Ryzen 1600X, 16GiB RAM, AMD RX570, Fedora 26 (clean install)

mesa-dri-drivers-17.1.7-1.fc26

Unigine Superposition Benchmark v1.0 (build 6184) Basic

Superposition and other OpenGL 4 (I guess) applications fail to render
correctly. It seems that only one of the rendering stages is being shown -- it
looks like the specular highlights from a cubemap or similar.

Tacoma (running on Unity) does the same.

Furthermore, there is a large disparity between the reported frame rate (30+)
and the actual frame rate I see (perhaps 1/3 or 1/4 of that).

Both worked perfectly in Fedora 25 (same hardware) with
mesa-dri-drivers-17.0.5-3.fc2.

I'm guessing this is a problem in the radeonsi driver.

Unigine Superposition works fine for me. Do you still have this problem with
more recent drivers? 17.1 has been unsupported for a while now.

Please consider this resolved.  At some point as mesa packages were upgraded,
this issue went away.  I'm now on 17.3.6, and cannot reproduce the issue.
Thanks.
