Most likely a sway bug. The code here is purely a resize. The only thing special thing mpv does is preserve the aspect ratio which probably confuses sway and causes that flickering. If you try on other compositors (like weston), this doesn't happen.

Not our bug and we don't need to track downstream issues.
