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.
