UnityLauncherQuicklistMenu clutter_actor_queue_relayout() warning

[Sebastien Bacher]

Binary package hint: unity

Running unity 0.2.12 on a GNOME session (ie running "unity" under GNOME, compiz is still running), when moving the mouse over the launchers I get those warnings displayed

"(unity:19156): Clutter-WARNING **: The actor 'UnityLauncherQuicklistMenu' is currently inside an allocation cycle; calling clutter_actor_queue_relayout() is not recommended

(unity:19156): Clutter-WARNING **: The actor 'UnityLauncherQuicklistMenuItem' is currently inside an allocation cycle; calling clutter_actor_queue_relayout() is not recommended

Some comments:

We shouldn't be creating new actors in the allocate cycle, rather just update the ones initially created. In the same way, no queue_redraws or queue_relayouts in the allocation cycle either.

The QuickList code needs to cleaned up in this regard. Also, there is a small trick to be done when updating cairo drawables, please see the panel/panel-background.vala to see how we have to handle the resizing of ClutterCairoTextures to avoid annoying Clutter (until Clutter gains support for doing it properly).

I'll look into the flickering issue and try to reproduce it here (nvidia-gpu, lucid). My maverick machine (intel-gpu) is currently not able to run any GL-app due to LP: #605825.

queue'ing of redraw()s and relayout()s for quicklist-items have been fixed and already merged into trunk. But some queue-relayout()s for quicklist-menu still remain (and hide themselves well), thus I marked it as "In Progress" and not yet "Fix Committed".

Improved/additional fix for clutk linked to this bug. Some issues of that branch still need to be ironed out though.

[David Barth (dbarth)]

Re-opening to get the additional branch in.

[Didier Roche (didrocks)]

reopening the ubuntu task so.
