[Bug 33790] [r300g] Black windows with opengl apps (ex. glxgears)

--- Comment #4 from speps dreamspepser@yahoo.it 2011-08-05 10:06:56 PDT --- With newer 7.11 release, this bug is still present. I managed to solve this by creating an .drirc file with:

<driconf> <device screen="0" driver="dri2"> <application name="all"> <option name="vblank_mode" value="0" /> </application> </device> </driconf>

It works in the same way with vblank_mode setted to 0 or 1, seems like vblank_mode is unsetted by default and cause the blank output.

Btw, glxgears FPS is still low with about ~400 FPS and glxgears_pixmap gives an even slower 2 FPS.
