KDE - Global Menu doesn't work properly (Unable to access Project Settings)

Hi. I want to thanks the improvements made on Unity Editor.

There’s a problem in the so called “Global Menu”, that doesn’t work properly in a modern KDE desktop.

How to reproduce?

  1. Add Panel “Application Menu bar” (It’ll add a empty panel with a global menu in it)
  • This will disable the menu in the apps, and replace it with the bar itself (like MacOS UI)
  1. Open Unity
  2. Try access Project Settings

I reproduced the problem using 2019.4.7f1 (LTS)
and 2020.1.1f1

I am using KDE Neon

I switched to Debian 10 Buster + XFCE, and the whole experience is so much better now.
