Mouse cursor position is freezed at last detected position when quickly moving mouse cursor out of mpv window #1000

Open Tsuchimikado opened 1 week ago

How to reproduce:

add video-sync=display-resample to mpv.conf
play video (not triggered when video paused)
quickly move mouse cursor out of mpv window

Mouse cursor position is fixed to monitor coordinates and not to mpv window. It can be checked by resizing mpv window which results to UI elements fading in/out, buttons highlighted, thumbfast showing thumbs etc.

I can't reproduce. Maybe I don't 100% get what you're describing. Video of it happening would help.

But either way, I'd guess this is an mpv issue? We just respond to cursor position events mpv sends us.

Sorry, tried it on fresh portable and found that hwdec=d3d11va is also needed.

mpv.conf

``` osc=no osd-bar=no border=no video-sync=display-resample hwdec=d3d11va volume=23 ```

I'd guess this is an mpv issue?

Cannot reproduce this in default UI and ModernX.

Video of it happening would help.

UPD: it is possible to reproduce this behaviour with hwdec=no or hwdec=dxva2 but more difficult than with hwdec=d3d11va
