wayland does not allow basic usage, or documentation is bad

5 problems can be seen with VLC:

• systray does not work, it stays a real window.
• the right button menus are scattered all over the place.
• in fullscreen, the progress bar can be moved around and remembers its position. not any more with wayland.
• there is a DVD menu normally, which is not visible at all here.
• preferences window is not properly refreshed any more

the developers of VLC say QT is guilty by offering no API to make the GUI as before:

would you be able to clarify? basically the message is QT platform abstraction (QPA) is useless.

(marking critical as i saw the detached menu placement with other applications as well, for wayland i guess it would be blocker)
