[Bug] Pop-up menus all over the place

Hi,

most of the time when I click something that displays a pop-up menu, the menu just shows on a random place on the screen (see the screenshot below).
I think this only happens when I have an external monitor connected to my laptop, but I’m not 100% sure, since I use an external monitor most of the time.

I’m on 8.1.4, but this behaviour was happening since I started using Ignition (I think that was 8.1.0).

Sorry for not reporting earlier,
regards,
JK
