Description

2 years ago
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170302120751

Steps to reproduce:

Have to monitors on windows 10.  In Windows Display settings, change one monitor text size to 125%.  Start firefox.  Move around to both screens.  The 125% font size of common for laptop displays at 1920-1080 resolution.


Actual results:

One of the screens will have a black box the entire size of the windows with a grey box for the menu and tab sections.


Expected results:

The window should look normal on both displays.  The problem goes away if all monitors are the same 100% text size.

I just found that in about:config changing layers.acceleration.disabled from false to true and restarting firefox fixed the problem.

I am no longer able to reproduce this issue with layers.acceleration.disabled set to either true on false.  So, I cannot determine if it fixed the black box on text size issue.  I have rebooted my system and don't see the problem with a monitor set at 125% text size and another monitor set at 100% text size.
