On a x86-64 host with a HD3870 running 2.6.39-2-generic (from ubuntu's oneiric) and

libdrm-2.4.25 and mesa compiled for 32bit:
OpenGL renderer string: Gallium 0.4 on AMD RV670
OpenGL version string: 2.1 Mesa 7.11-devel (git-390196e)

I get lightning artifacts with r600g on a couple of games from frozenbyte.com, most notably when using the flashlight in shadowgrounds.

Here's a apitrace capture: http://static.hackmii.com/dhewg/shadowgrounds.apitrace.xz

When replaying it via glretrace there're some weird window resizes, but the issue is visible when it doesn't crash :)

The issue does not exist with swrast.

It's rendering fine on my redwood, so I guess this is hardware specific.
Comment 2 Christoph Brill 2015-11-18 20:12:18 UTC
The apitrace is no longer available and it was tested against an old version of mesa. Please retest and provide an apitrace if possible.

Andre Heider, Ubuntu Oneiric 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
