[Mesa-stable] [Mesa-dev] [PATCH] egl/x11: Send invalidate to the driver on dri2_copy_region

[Deepak Rawat]

Similar to what is done in dri2_x11_swap_buffers_msc send invalidate
to the driver because egl/X11 is not watching for for server's
invalidate events. The dri2_copy_region path is trigerred when
server supports DRI2 version minor 1.

Tested with piglit egl tests for regression.
