1328931 - Using hardware acceleration causes windows to go black when dragged to different monitor

Status: UNCONFIRMED

(Core :: Graphics, defect, P3)

Description

[lukas.seiler]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161208153507

Steps to reproduce:

Dual monitor setup, Win10 on laptop with nvidia optimus

1. open firefox (hardware acceleration enabled)
2. drag firefox window from internal screen to external screen and then (without releasing the mouse button) to the top of the external monitor to maximize it instantly


Actual results:

the content area of firefox turns black (each time) and the menu/tab area turns white.
only way to get it to normal berhaviour again is dragging it back to the internal screen. 
The part of the firefox window that is on the internal screen is instantly showing the content again, while the other part stays black until the whole window (or more than half) have been dragged to the internal screen.

funny sidefact:
if i release the mouse button once before maximizing the window on the external screen, the issue does not occur


Expected results:

the content should be displayed normally and the window should not turn black
