<request name="discard_constraints" since="7">
<description summary="hint that existing constraints should be discarded">
This request hints to the compositor that the constraints of content
updates (CUs) that are currently enqueued in the surface queue should be
discarded. See the description of wl_surface.commit for the definition
of CUs and per-surface queues.
This hint is double-buffered state, see wl_surface.commit. It applies to
all CUs that are enqueued at the time of the wl_surface.commit request
and to their dependencies, excluding the CU created by the
wl_surface.commit request itself.
Clients may use this request to hint that they prioritize the
application of the following CUs over previously committed pacing and
timing constraints.
It is compositor policy which constraints are discarded.
