Research direction
Start by reviewing the linked mpv.log alongside the reproduction details for Wayland scaling at 300% on a 3840x2160 display. Trace the reported window dimensions and determine how the behavior should preserve the expected 3840x2160 size; done means the video opens at that size under the stated setup.
