Picture of Krita running when the plasmoid "Global Menu" is enabled (here, it is on the top left of the screen, at the right of the desktop switcher plasmoid)

The menu bar doesn't show up when the global menu is enabled on KDE Plasma.
It doesn't show up anywhere, nor the application or the global menu widget have the menu bar of Krita.

I'm currently running on Arch Linux (fully up-to-date) with the KDE Plasma 5.16 desktop environment. I have no way to get it back "normally", I have to remove the global menu plasmoid, go to the configuration file of Krita (kritarc) and set the menu bar value to true, and restart Krita. After doing that, when if you check the back the configuration file, the menu bar line is removed. If you try to enable it when you have the global menu enabled, it will automatically return to false and the menu bar doesn't appear in Krita.


Here are the steps to reproduce this bug (very easy) :

-Be on KDE Plasma (the latest version if possible)
-Add the global menu plasmoid to anywhere on your desktop or on your panel
