(xfce4 desktop) window manager consumes fullscreen hotkey, Fullscreen checkbox is not updated

[ronso0]

Bug Description

If the window manager fullscreen hotkey matches Mixxx default fullscreen hotkey (F11), that is consumed by the window manager and MixxxMainWindow::slotViewFullScreen is never called.

Fullscreen is toggled correctly, only downside is that the View > Fullscreen action is not updated, i.e.

• go fullscreen with hotkey
• Fullscreen menu toggle is unchecked
• needs to be clicked twice to exit fullscreen
• then it's possible to run into crash when pressing menu hotkey (Alt+F) in fullscreen mode on Linux with a global menu #11320 if the desktop has a global menu

Version

2.3.3 and newer

OS

Ubuntu Studio 20.04.5 with xfce4 dektop incl. xfwm4
