Bug #: 44696 Summary: Rendering glitch in ShaderToy Nautilus 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
Created attachment 55460 --> https://bugs.freedesktop.org/attachment.cgi?id=55460 capture of the canvas, showing the rendering bug
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 Nautilus 3. click 'Load'
Expected result: the blueish surface should look smooth
Actual result: rendering is littered with small dark square-ish spots that move continuously with the animation.

--- Comment #2 from Andreas Boll andreas.boll.dev@gmail.com 2012-09-10 11:42:37 UTC --- As you can see in attachment 66920 the rendering is fine on current firefox nightly 20120910 and current mesa 9.1-devel (git-e81ee67)
WebGL Renderer: X.Org -- Gallium 0.4 on AMD RV770 -- 2.1 Mesa 9.1-devel (git-e81ee67)
Additionally I have tested it with mesa 8.0.4 With current mesa stable the rendering bug is also gone.
So I'm closing this bug. Feel free to reopen if the rendering issues persist for you.
btw: The demo is a little bit laggy. radeontop shows that the demo is gpu bound on my rv770 (~100% graphics pipe usage)
