Multi-monitor with different refresh rates causes dropped frames.

mpv 0.34.1
Arch
Arch Official repositories
Kwin
Nvidia 495.46

Reproduction steps

While using multiple monitors with different refresh rates, use display-resample, starting the video and going into or out of fullscreen repeats the issue.

Expected behavior

mpv will pick up the refresh rate of the monitor where the window is and have no significant amount of dropped, mistimed and delayed frames.

Actual behavior

mpv picks the wrong refresh rate, and shows a lot of mistimed/delayed and dropped frames during the first few seconds, it gets stable after some time but the estimated refresh rate continues to show the refresh rate of the other monitor.
The issue happens every time in the 144Hz monitor, but i only saw the issue in the 60Hz monitor once while testing on KDE. I was also able to replicate this issue on GNOME Wayland and Xorg, on Wayland the 60Hz monitor would have the issue more often.
This is similar or possibly identical to #9339 but on Linux.

Sample files

Anything that I've tested caused the issue.

Start by reproducing the issue with display-resample on multiple monitors using different refresh rates, including fullscreen transitions under Wayland and Xorg. Review the attached output.txt and compare the reported refresh rate and frame timing on each monitor; done means the active monitor is selected and dropped, mistimed, and delayed frames no longer occur.
