Xfce4 Compositor Troubleshooting information

[Phahou]

When using xfce4 one might think that the program doesnt work and might switch to the Tk version which works out of the box as no compositing is involved (as far as I say it).

Only 'gotcha' to troubleshoot is that the mpv window should be set to 'always below other windows' which might be helpful for other xfce4 users.

Tested on xfce 4.18, dual monitor. Another gotcha: As xfce4 uses xrandr iirc on a dual monitor setup with the right one being in the vertical position the text on fullscreen on the wide monitor(left) is in an area which cant be seen as xrandr spans a rectangle over both monitors displaying black on the non-viewable areas. Currently the text will be shown a few pixels above the bottom edge of the monitor.

If however viewed on the vertical monitor the text appears on the left about in the middle of the screen

EDIT: When using both monitors in wide mode the text can only be seen on the left but that's fine imho
