Description Piotr Mierzwinski 2023-10-31 15:56:48 UTC 
SUMMARY
As in subject. I cannot turn on full screen in mplayer. Keyboard shortcut F does nothing. Option passed in command does nothing (the same in config file). Nevertheless all works fine in X11 session. I tested in xfce4.
BTW. I can maximize window.

In my ~/.mplayer/config I have only setting of code page.
I don't use any options starting mplayer with video file.


STEPS TO REPRODUCE
1. mplayer video file
2. Press "F"
3. 

OBSERVED RESULT
Happens nothing

EXPECTED RESULT
I should get full screen with opened video file.

Works for me with mplayer-1.5.1 on Fedora KDE run on Plasma 6. If you're using an older version of mplayer, it might be that it doesn't have Wayland support yet. Regardless, this is an app issue, not a problem with Plasma or KWin.

Thank you for checking.
Seems this is problem of distribution I use.
I use mplayer version 1.4. It looks like that n Neon Unstable Edition there is an old version
