Description Christoph Brill 2007-05-18 02:21:43 UTC
When I run blender 2.44 on mesa 6.5.2 without "disable_lowimpact_fallback" I get strange yellow "borders". Enabling the "disable_lowimpact_fallback" it gets rendered correct.

ok, I must admit rendering in software even looks better. as you can see the border around file is smooth.
Comment 4 Jacek Poplawski 2007-05-18 02:32:09 UTC
Press tab and try to select vertices with b. Without fallback you will notice lots of rendering errors.

And the whole test against latest git, the line is now green instead of yellow. But the problem persists.

You could try to find out exactly which fallback this is related to. See the
r300Fallback function in r300_render.c.
Comment 7 Lukasz Krotowski 2007-07-05 17:00:44 UTC
It seems that problem is fixed in latest git.
Comment 8 Christoph Brill 2010-10-17 01:39:44 UTC
No longer happens (neither r300c nor r300g)
