Description gsr.bugs 2011-05-22 21:46:39 UTC
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.

Is this still an issue with current Mesa git?

I playing with supertuxcart today.The game is boring so I don't test all tracks,but I cannot see any rendering errors with hyperz on. I run it on full details in 1600x1200 and it looks good for me.

mesa-git (today)
xorg-server-git
kernel 3.6.9
kde 4.9.80 (kwin effects enabled)

Sorry, no easy access to try with the RV360 currently. If Tomasz P. says
that no more lines or squares, great. If the issue reappears, we can reopen
it or fill a new report. Thanks.
