Subject: [PATCH] st/dri: Clear drawable texture_mask in
 dri2_invalidate_drawable
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This makes sure that dri_set_tex_buffer2 -> dri_drawable_validate_att
will re-create the front left attachment buffer after the drawable got
invalidated.

Fixes window contents not updating until the window is resized when
using DRI2 PRIME.
