Video representation of the bug

SUMMARY
Opening an application that uses a menu bar at the top (like libreoffice) makes it spawn in the wrong place.

STEPS TO REPRODUCE
I was not able to re-create the issue within a VM.
I would guess the issue is something to do with multi-monitor setup

OBSERVED RESULT
Starting LibreOffice, dragging the application to the left monitor. As soon as the application is half-way through to the other screen, the menu (that should have spawned in the application at the top) spawned on the task bar, to the left for all applications on the bar.
Once the left monitor is disabled, the menu isn't rendered at all.
Please see attachments for visual representation of the issue.

EXPECTED RESULT
Menu should have appeared on top of the application, and stayed there while other programs have focus.
The menu should not be created when it's on the left monitor, it shouldn't appear on the task bar.
