             Bug #: 44695
           Summary: Rendering glitch in ShaderToy Monjori demo with Mesa
                    7.11 Gallium 0.4 AMD RV710
    Classification: Unclassified
           Product: Mesa
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: bjacob@mozilla.com


My setup: Ubuntu 11.10 x86_64, Mesa 7.11, Gallium 0.4 on AMD RV710.

Steps to reproduce: in Firefox (I'm on Firefox 12 / Nightly but that shouldn't
matter):

1. Go to this URL:
   http://www.iquilezles.org/apps/shadertoy/
2. in the 'Presets' drop-down, select Monjori
3. click 'Load'

Expected result: purple-colored glittery wobbly surface should fill the whole
canvas

Actual result: the purple-colored stuff is only painted in the lower-left
corner of the canvas, the rest of the canvas stays black.

capture of the canvas, showing the rendering bug

Notice how the limit of the purple are is slightly oblique... maybe that
contains a clue as to what the problem is.

This was tested against an old version of mesa. Does this still persist on mesa
11.0.x or later?

Benoit Jacob, Ubuntu 11.10 reached EOL on May 9, 2013. For more on this, please
see https://wiki.ubuntu.com/Releases.

If this is reproducible in a supported release, it will help immensely if you
filed a new report with Ubuntu by ensuring you have the package xdiagnose
installed, and that you click the Yes button for attaching additional debugging
information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.
