           Summary: radeon 6.14.0: OpenGL rendering broken in some
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: alexandre.f.demers at gmail.com

I'm not sure if the problem comes from mesa, kernel or the radeon driver
itself. However, when installing radeon driver 6.14.0 with kernel 2.6.37
(vanilla) and using latest mesa git version, some applications don't render
correctly anymore.

I use RendererFeatTest almost everyday to test the latest mesa version.
However, when I installed radeon 6.14.0, the application slowed down and some
elements are not rendered correctly anymore. Reverting to 6.13.2 fixes it. So
the problem doesn't come from mesa nor kernel itself.

I'm running Ubuntu 10.10 64bit, using XServer 1.9 and vanilla kernel 2.6.37.

I could test with latest 2.6.38-rc to see if this combination works.

I'll add the rendering screenshoots from RendererFeatTest with 6.13.2 and
6.14.0 driver.
