790582 - OMTA needs to mediate main thread updates

Status: NEW

(Core :: Graphics: Layers, defect)

Description

[Benoit Girard (:BenWa)]

Attachment: Modified test case

See attachment from bug 790567.

STR: 
1) Double click on a tab
2) Notice that the animation will run backwards for a frame

I think what is happening is that the compositor is running the animation while the main thread is blocked. Once the main thread finally produces its frame it causes the frame to run backwards. I think we need to somehow mediate the update to prevent these glitches.

The patches in bug 780692 make this a little better.  I don't have the final patch yet, but I think that bug may fix this.

The bug assignee didn't login in Bugzilla in the last 7 months, so the assignee is being reset.
