#1006 Simple UI: toolbar disabled itself randomly

[Strangiato]

Hi
I use qmmp 1.3.3 on Arch Linux running Gnome 3.32.2 desktop environment.
Sometimes the toolbar disables itself if the simple UI is used.

Steps to reproduce:

1. enable simple UI in qmmp preferences (plugins section)
2. restart qmmp
3. if the toolbar is not enabled, enabled by right-clicking on the menu bar and checking "Toolbar"
4. restart qmmp a few times: at some point the toolbar will be disabled after you restart qmmp

Correcting the step 3:

1. if the toolbar is not enabled, enable it by right-clicking on the menu bar and checking "Toolbar"

Start qmmp from command line and try to reproduce this issue. May be application will print some thing useful.

I have just noticed that the toolbar is only disabled if I close qmmq by clicking X button
in the upper right corner.
The toolbar is never disabled if I close qmmp by pressing ctrl+q.
Maybe it's a problem related to this Qt bug

Try wayland support in Qt5: https://wiki.archlinux.org/index.php/Wayland#Qt_5 It should work wthith qsui. But do not forget to disable hotkey plugin. It causes program to crash.

Thank you. Qmmp works as expected while running natively on Wayland.
