Subject: mesa: Remove unnecessary FLUSH_VERTICES in bind_buffer_range
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=291ae4e6396872679fef72ed4fdd46fb7f945c3d;p=mesa.git

mesa: Remove unnecessary FLUSH_VERTICES in bind_buffer_range

It isn't necessary to call FLUSH_VERTICES from bind_buffer_range,
because transform feedback buffers are not allowed to be changed when
transform feedback is active.

Thanks to Marek Olšák for pointing out this bug.
