I have a fix for that on my local branch, that's why I didn't see that.

Fixed by https://github.com/mpv-player/mpv/pull/14127 you can try build from there

open a new issue, this one is for windows and almost definitely completely unrelated to yours.

can also reproduce with option --no-title-bar --window-maximized=yes --auto-window-resize=yes.

• load two videos with different aspect ratios to the playlist, such as 16:9 and 4:3
• run playlist-next

auto-window-resize will resize the maximized window, then small title bar appears.

I think auto-window-resize should not work on maximized window, just as it doesn't work on fullscreen.
