Subject: r300g: set the correct offset in a colorbuffer surface
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=07190888bdc41f53bf8ea30c9e2ee4a61b42d802;p=mesa.git

r300g: set the correct offset in a colorbuffer surface

Suggested by Joakim Sindholt.

Also, put flushing of colorbuffers _before_ the framebuffer state setup,
suggested by docs.
