Reproduction Steps

Install Manjaro with latest KDE Plasma, install mpv, open some video. Exit fullscreen if in fullscreen.

When you click on window, cursor immediately goes into "Move window" mode. When clicking with mouse, it goes back fast enough to register second click in normal mode and go into fullscreen. (Although still not perfect, sometimes it doesn't register second click) When clicking with touchpad, it goes into "Move window" mode and stays there for 0.5-1 second, so double click can't register and you can't go into fullscren.

upd. if you click suuuuuper fast with touchpad, you can manage to double click before cursor goes into "Move window" mode :3

Expected Behavior

Working

I expect that when I click, cursor doesn't go into "Move window" mode, but if I click, hold and then move cursor while holding, it goes into "Move window" mode. If I'm not wrong, before latest Manjaro KDE Plasma update (KDE 5 -> KDE 6), it was working pretty good. Not sure if issue should be fixed on their side or on mpv side.

Actual Behavior

Not working

Log File

Sample Files

No response

I carefully read all instruction and confirm that I did the following:

[X] I tested with the latest mpv version to validate that the issue is not already fixed.
[X] I provided all required information including system and mpv version.
[X] I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
[X] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
[X] I attached the full, untruncated log file.
[X] I attached the backtrace in the case of a crash.
