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.
