Summary: Noise in some tracks in SuperTuxKart (HyperZ related) Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: gsr.bugs@infernal-iceberg.com

Some tracks of STK show noise in two forms. One is thin lines, in yellow over white surface, for example, like if you were modelling the track and wanted to see the polygons edges. And the second is small squares or rectangles where karts' shadows appear or also near polygon edges, where walls and grounds meet, for example.

It's rather hard to capture on a picture (slow computer, karts sliding/shaking a bit even if stopped, so the noise flickers constantly) but the square one is like some HyperZ bugs, you can guess the colour comes from other colours in the same track. When RADEON_HYPERZ is not set, things render as they should. This is in a RV360 card, not R5xx like the other reports.
