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.
Created attachment 55459 [details] 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?
