1409318 - Changing video to full-screen takes two steps transition, instead of directly one move

Status: NEW

(Core :: Graphics, defect, P3)

Description

[Alastor Wu [:alwu]]

Testing on my own m-c *debug* build on 58.0a1 (2017-10-16), OSX 10.11.4.

On the attachment, you could see the process of changing video to full-screen is not very smooth, it would be obviously two steps transition. Sometime, the issue would also happen when you exit full-screen.

Also, see some suspicious log,
