Reproduction Steps

• Set clipboard-monitor=yes
• Open mpv in idle or with an image
• Copy anything to clipboard
• Hover over the mpv window

Expected Behavior

Observing clipboard should update without hovering over the window even when no video is playing.

Actual Behavior

As per https://github.com/mpv-player/mpv/discussions/15565#discussioncomment-11668922:

Is it expected that on Windows(10) observing clipboard does anything only when mpv is playing a video(can be paused) ?

On my side when its in idle or 'playing' an image, it requires hovering over the window to actually update. Docs don't mention anything about it in clipboard-monitor, but in the PR there was something about Wayland being only updated on window focus, nothing about Windows and hovering over it though. Should this be a potential bug report ?

However, i had it the other way around in the mentioned working scenario, the video can't be paused for it to work.

Log File

clipboard_Idle.txt
clipboard_Video.txt

Sample Files

mp.observe_property('clipboard/text', 'native', function (_, clipboard)
        mp.msg.info(clipboard)
end)

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

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• 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.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

Reproduce the report with clipboard-monitor=yes and the supplied Lua observer, testing idle, image, paused-video, and playing-video states on Windows 10. Compare the attached idle and video logs with the expected behavior: clipboard changes should be observed without hovering over the window, and verify the result in each state.
