             Bug #: 50325
           Summary: Glyphy bad render on r600g (software render is fine)
    Classification: Unclassified
           Product: Mesa
           Version: 8.0
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: edwin+mesa@etorok.net


Created attachment 62078
  --> https://bugs.freedesktop.org/attachment.cgi?id=62078
apitrace (cf. https://github.com/apitrace/apitrace/tree/1.0)

I just tried Glyphy on r600g and the output is very bad.
Don't know if its Glyphy bug or Mesa bug, but if I force software rendering in
Mesa then I do see the output.

Attached screenshots of bad (r600g) and good (software render).

The bad render was obtained by:
demo/glyphy-demo

The good one:
LIBGL_ALWAYS_SOFTWARE=1 demo/glyphy-demo

I tested on:
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV730
OpenGL version string: 2.1 Mesa 8.0.2
OpenGL shading language version string: 1.20

I'll try to test on mesa git later to see if its still an issue there.

Also attached is a an apitrace, and the bad render can be reproduced with:
build/glretrace lt-glyphy-demo.trace

The good render (initialization a bit slow, but works):
LIBGL_ALWAYS_SOFTWARE=1 build/glretrace lt-glyphy-demo.trace

The source code for Glyphy can be found here:
