The former is indirect software rendering in the X server, the latter is direct rendering with the r300 driver falling back to software, which is known to be flaky. > Secondly, error messages: > I see an error message related to software fallback; apparently the r300 DRI > can't handle something called stippling (ctx->Line.StippleFlag). So, does running the app with disable_lowimpact_fallback=true (Which should be the default though in the version of Mesa you're using) make the message and/or corruption disappear? > Finally, reproducing the problem:Thirdly > This problem would probably be easier to diagnose if it was observed in a > simple demo program.

This is due to gearbox; it basically leaves the contents of the top left corner undefined. The sketchup problem is probably unrelated. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev
