1352842 - First (re-)launch of firefox breaks HDMI output

Status: RESOLVED INACTIVE

(Firefox for Android Graveyard :: Screencasting, defect)

Description

[f.st]

User Agent: Mozilla/5.0 (Android 5.0.1; Mobile; rv:52.0) Gecko/52.0 Firefox/52.0
Build ID: 20170324081508

Steps to reproduce:

I use S4 Value Edition in dock connected to TV over HDMI. Use Quit from menu (requires any one datatype to be selected for deletion on quit). After termination of firefox start it again.
Alternatives for reproduction: reboot mobile and start firefox or clean reinstall and start firefox.


Actual results:

Shortly after UI startup which looks normal - a second later or so the reasonable UI gets replaced by a white rectangle not fitting to screen dimensions in a black margin. Nothing else is visible.
It's not limited to Quitting, also a start after reboot, and a start after app installation brings this reproducible result. Tested up to 53beta7. Problem exists a longer time already.
I selcted General for component as I don't know which is HDMI related.
In this state it's possible to undock and seeing a normal firefox UI - docking back again problem still there. Only thing from HDMI right mouse click to finish firefox. Then starting again works because it was only in background and not terminated.


Expected results:

HDMI output shouldn't be corrupted restarting after using quit - or cold start - or first installation. Firefox is the only App showing this behaviour.
