Description mj.wilson.uk 2017-09-09 15:55:10 UTC 
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.
