Subject: [PATCH 1/2] clutter: Refactor code marking actors dirty for paint()
|
||||
|
||||
Simplify the function arguments (the origin is just the actor that
|
||||
the function is originally called from), and make it also handle
|
||||
marking as dirty the actor that got the redraw queued up explicitly.
|
||||
|
||||
This makes it a single place where priv->is_dirty is being enabled.

Subject: [PATCH 2/2] clutter: Keep actors dirty if a redraw was queued up
|
||||
during paint()
|
||||
|
||||
In the right combination of circumstances, and given 2 actors (parent
|
||||
actor P with an offscreen effect and child actor C), we may have the
|
||||
following situation happening:
|
||||
|
||||
- A redraw is queued on the actor C, actors C and P are marked as
|
||||
priv->is_dirty and priv->propagated_one_redraw.
|
||||
- During paint() handling we paint actor P, priv->propagated_one_redraw
|
||||
is turned off.
|
||||
- We recurse into child actor C, priv->propagated_one_redraw is turned
|
||||
off.
|
||||
- A new redraw is queued on actor C, actors C and P are marked as
|
||||
priv->is_dirty and priv->propagated_one_redraw.
|
||||
- The paint() method recurses back, actors C and P get priv->is_dirty
|
||||
disabled, priv->propagated_one_redraw remains set.
|
||||
- At this point queueing up more redraws on actor C will not propagate
|
||||
up, because actor C has priv->propagated_one_redraw set, but the
|
||||
parent actor P has priv->is_dirty unset, so the offscreen effect will
|
||||
not get CLUTTER_EFFECT_PAINT_ACTOR_DIRTY and will avoid repainting
|
||||
actor C.
|
||||
|
||||
The end result is that actor C does not redraw again, despite requesting
|
||||
redraws. This situation eventually resolves itself through e.g. relayouts
|
||||
on actor P, but may take some time to happen.
|
||||
|
||||
In order to fix this, consider actors that did get a further redraw
|
||||
request still dirty after paint().
