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.
Created attachment 10011 [details] with_fallback.png A picture says more then 1000 words.
Created attachment 10012 [details] without_fallback.png And a second picture explains the problem.
Created attachment 10013 [details] software.png ok, I must admit rendering in software even looks better. as you can see the border around file is smooth.
Press tab and try to select vertices with b. Without fallback you will notice lots of rendering errors.
Created attachment 10015 [details] with_fallback_latest_git.png 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.
It seems that problem is fixed in latest git.
No longer happens (neither r300c nor r300g)
