1207674 - UI repainting seriously wrong before going fullscreen

Status: RESOLVED DUPLICATE of bug 1137009

(Core :: Graphics, defect)

Description

[Cam]

Attachment: Screen Shot of ui hang.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20150921004016

Steps to reproduce:

Start Firefox
go fullscreen
quit firefox while fullscreen
restart Firefox


Actual results:

Firefox paints the ui properly for a few miliseconds then stops even if the ui is unusable, and doesn't repaint when interacted with until I enter fullscreen.

Leaving fullscreen does not reintroduce the issue. And technically the UI is still responsive, but you can't see what you are clicking on.


Expected results:

Firefox ui is painted as usual.

Does this bug still exist in Nightly?

Comment 2

On Windows, there is a similar behaviour, after restarting Firefox previously set in FS mode, Firefox doesn't paint the content page (blank page) during a few ms when reaching FS.

I expect all issues like this (opening window or quiting the browser when in fullscreen causes the UI be broken) should be fixed by my patches in bug 1137009.

Bug 1137009 says it's resolved fixed, but this is still occurring in Aurora/FFDE 43.a2. Has the patch only made it to nightly or is it in aurora too? Because I don't see the issue in nightly (though I am using a new profile in nightly).

That fix is currently only in Nightly, but I've requested an uplift to Aurora, which haven't been granted yet.
