FPS estimate when on secondary display is wrong, possibly based on the primary monitor?

Important Information

Note: May be related to?: https://github.com/mpv-player/mpv/issues/11465

When having the mpv window on the secondary screen it estimates the fps based on the primary screen:

Screenshot

Provide following Information:

• mpv version mpv 0.35.0-326-ge1727553
• Windows Version: Microsoft Windows 11 Pro, 10.0.22621, Build 22621
• Source of the mpv binary: https://github.com/shinchiro/mpv-winbuild-cmake/releases/tag/20230317

Reproduction steps

Open MPV via: >mpv --no-config -v -v --log-file=debug.txt --video-sync=display-resample --vo=gpu-next ytdl://https://www.youtube.com/watch?v=7ePaVk7TKGM

Move video from 180Hz main screen to another screen that is 60Hz.

Expected behavior

Estimate should be ~60Hz

Actual behavior

Estimate is 180Hz, taken from the wrong monitor.

Can anyone confirm this?

I can confirm this in Linux (gnome wayland), too. Mpv will take my laptop screen's 60hz fps even if it starts directly on my external 120hz monitor. I'll have to move it out of my external monitor then move it back for it to correctly detect.

That's not supposed to happen, but from that description it sounds like a GNOME bug (sending erroneous surface entrance events on startup). It's not related to OP though which is windows and totally different.

I'll check on KDE later, and see if I need to submit a new issue. Thanks for maintaining this beautiful project!

Anyone got any more info on this, it's quite annoying.
