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.
