Watch-later from fullscreen window contains wrong border information

[christoph-heinrich]

Important Information

Provide following Information:

• mpv 0.35.0-363-gc50f536bd1
• Arch Linux
• compiled from source
• KDE Plasma 5.27.4 on Wayland
• Mesa 23.0.2

Reproduction steps

1. Create a directory with a mpv.conf containing border=no
2. mpv --config-dir=<path to aforementioned directory> <path to some video file>
3. Fullscreen the video
4. Quit with Shift+q to save watch-later information
5. Run the same mpv command again
6. Exit fullscreen

Expected behavior

Window has no border

Actual behavior

Window has a border.

The file with the watch-later information (~~/watch-later/<hash>) contains border=yes instead of border=no.

Log file

log from first run
log from second run

This is almost certainly because the border option works weirdly on wayland. Although I wouldn't have expected this to happen.

[christoph-heinrich]

Apparently border even gets set to true while in fullscreen, so it makes sense that watch-later would act that way.

It looks like the compositor sets the border when going into fullscreen. That's pretty weird.
