|
When a badly behaving ClutterActor implementation manages to invalidate
|
|
the allocation after the layout phase and before painting, we have no
|
|
idea where the actor should be painted without running the whole layout
|
|
machinery again.
|
|
|
|
For paint volumes in this case we pretend the actor covers the whole
|
|
stage and queue full-stage redraws. When updating stage-views, we're
|
|
also handling this case, but not in the most graceful way. Just like
|
|
with paint volumes, we should assume an actor without a valid allocation
|
|
is simply everywhere, so set priv->stage_views to all available stage
|
|
views in that case.
