Subject: mesa: Only end render-to-texture at bind time for drawbuffers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a1fd13fff18f95b83fabf3428689ff47abb5c5f8;p=mesa.git

mesa: Only end render-to-texture at bind time for drawbuffers.

If we're only starting for new draw buffers, why would we end for old
read buffers along with draw buffers?
