           Summary: textures on Earth in Celestia contain pixels from
                    other windows
           Product: Mesa
           Version: 7.10
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: acelists@atlas.sk

See the blue dotted band around the planet - it is a window titlebar.

Textures on the planet Earth are rendered garbled with data pixel taken from
other windows (programs), probably taken from released GPU memory. Note it only
happens on Earth. The garbled texture is not the planet surface one, but it is
the clouds layer. That is loaded from a file that is 1024x512.

It does not happen when lowres textures are selected. Then a 128x64px file is
used for the clouds.

Ah, this is on Radeon HD4350, Mesa 7.10.2 R600c, kernel 2.6.38.4, KMS.

It was quite good in 7.11 with R600g. But it is back with even worse effects on
a nightly version before 8.

Can you bisect r600g?

Still an issue with released mesa 8.0 or with mesa git ?

Yes, happens with 8.0-rc2 (kernel 3.2.5, ati 6.14.3, libdrm 2.4.30).
Even got this:
radeon: The kernel rejected CS, see dmesg for more information.
[drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!

Will try git later after some weeks.
But it was fine in 7.11 but I can't do bisecting right now.

Mesa 8.0 is pretty outdated, could you please retest with a more recent version
of mesa?
