Bug#410934: mesa: Rendering completely garbaged on r300

Hello Michel.

The hell? I commented that option out and restarted (since when is logging out
and in again not enough for this?). And what do I say: everything works
perfectly. And even faster than before. No fragments, no nothing. 3D just looks
great now.

Why I actually activated that option? I followed the suggestions from the radeon
manpage:

>        Option "FBTexPercent" "integer"
>               Amount of video RAM to reserve for OpenGL textures, in percent. With EXA,
>               the remainder of video RAM is  reserved  for  EXA  offscreen  management.
>               Specifying  0  results  in all offscreen video RAM being reserved for EXA
>               and only GART memory  being  available  for  OpenGL  textures.  This  may
>               improve  EXA  performance,  but  beware  that  it may cause problems with

And so far I didn’t have any trouble. Maybe the driver did change somehow?
Anyway, you really made my day, so thank you very much!

(Yep, please mark this report as fixed. I’ll try upgrading to the latest mesa
again and if you hear nothing from me, then everything worked out well.)


Regards, Mathias
