          Priority: medium
            Bug ID: 59172
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [r300g] flashing and corruption with MSAA 6x and
                    1920x1080
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: fabio.ped@libero.it
          Hardware: x86 (IA32)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r300
           Product: Mesa

When running some applications such as supertuxkart 0.8 with a high resolution
(1920x1080) and MSAA 6x the screen flashes, shows massive corruptions and gets
very slow. Just changing MSAA to 4x the problem is no longer reproducible.

Tested on current git with:
r300: DRM version: 2.18.0, Name: ATI RV530, ID: 0x71c5, GB: 1, Z: 2
r300: GART size: 509 MB, VRAM size: 256 MB
r300: AA compression RAM: YES, Z compression RAM: YES, HiZ RAM: YES

--- Comment #1 from Alex Deucher <agd5f@yahoo.com> ---
This is probably related to memory bandwidth since MSAA compression is not
currently implemented.
