Public bug reported:
When using the Wayland session, the screen will sometimes randomly flash
(usually after opening an application). After the screen flashes, the
open windows will often end up in different positions or in different
monitors. Video of the issue is attached.
Expected Behavior: For the LibreOffice window to stay on the right
monitor and to not change size or position.
Actual Behavior: The LibreOffice window opens to the right after I open
Lollypop.
This issue doesn't exclusively happen while LibreOffice or when opening
Lollypop, however, opening Lollypop is one of the most predictable ways
to trigger the bug. The majority of the time, the bug occurs in the
middle of regular use without me triggering anything.
I'm using a dual monitor set-up, with a 2560X1080 monitor at 1x scaling hooked
up to a 4K Hi-DPI laptop screen at 2x scaling.
