Bug#623969: libgl1-mesa-dri: Major gallium 2D performance bottleneck (most noticable with compiz)



Hi,

you could give upstream master a shot, using instructions available at:
  http://pkg-xorg.alioth.debian.org/howto/build-mesa.html

(which needs some tweaking as far as radeon is concerned, but you
might find your way through radeon/r* options/drivers)

If the issue persists, please get in touch with upstream developers:
  https://bugs.freedesktop.org/ (product: Mesa)

and let us know the bug number/URL so that we can track it.

Thanks.

KiBi.
