           Summary: "the timeless" demo in wine: Red dot rendered that

           Product: Mesa
           Version: git
          Hardware: Other
                OS: All

screenshot: radeonsi with the red dot

The program is THE TIMELESS, can be downloaded from here: http://mercury.sexy/

It's for windows, but uses OpenGL 4.3 and needs these overrides to work in
wine:
MESA_GL_VERSION_OVERRIDE=4.3COMPAT MESA_GLSL_VERSION_OVERRIDE=430

Here is an apitrace of the first few seconds, 34MB:
http://haagch.frickel.club/files/timeless.trace
(For some reason when replaying it resizes the window to a massive size. The
actual image is in the lower left)

Notice the big red dot in the middle. It only happens on radeonsi. On intel
there is no red dot, but a small black dot.

Hardware:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Wimbledon XT [Radeon HD 7970M] (rev ff)

Latest mesa git.
