Subject: intel: Flag NEW_BUFFERS when changing draw buffers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bcf63dbbd8fd31b724294b34a62a0e6c565dce87;p=mesa.git

intel: Flag NEW_BUFFERS when changing draw buffers.

There were entries to this function (most imporantly, prepare_render
-> update_renderbuffers) that wouldn't have had NEW_BUFFERS set, but
brw_wm_surface_state (the i965 state tracking the drawing regions)
expected this to change.
