Description

I face a problem with my 3 monitors configuration (a Thinkpad T440 laptop with a dock and two secondary monitor plugged on it)
I can’t get “full screen” window on secondary screens. Here is what I get after clicking on the “expand” button of each window.

Budgie version

budgie-desktop 10.5.1

Operating system

Ubuntu 20.04

Steps to reproduce the issue

Configure 3 monitors like this, with top panel on the lower screen 1

Actual result

Can't get windows full screen on screen 2 and 3, except by reducing the size and then drag and drop the corners to fit the screens.

Expected result

Additional information

A discussion started here https://discourse.ubuntubudgie.org/t/unable-do-get-full-screen-windows-on-secondaries-monitor/4861
So I can get it work if I move the panel at the bottom of the main screen.
