When window have ontop property then everything is ok. I'm using this as a workaround.

I have this same issue but on linux, vlc plays the same video fine so it's not my system

Please provide a log file, it's impossible to help otherwise. The issue template should've told you how to get a logfile, but you can use --logfile=mpvsucks.log for it.

Also try gpu-api=vulkan

What I found today that when app is runned as administrator then problem doesn't exists. testAdministrator.txt testNoAdministrator.txt. These are two logs with and without admin run.
