On my Mac Mini M1, I've noticed that double clicking, which (coming from VLC, my preferred behavior) should toggle the screen to full screen, then back to a smaller window, when I double click repeatedly. However, in both Iina 1.2.0 build 129 mpv 033.0 and a fresh copy of mpv 0.32.0 I just downloaded, this does not work reliably, usually making the screen go full screen, then back to window, only one time each. I need to quit and reload the program if I need to back into full screen by double clicking.

Note that I have been using Use Legacy Full Screen. The problem seems to not happen when I turn off Use Legacy Full Screen and restart the computer. So it seems to be related to that.

System and IINA version:

• macOS
• M1 Mac Mini running the current Apple beta release of 12.3 (21E230)
• IINA
• 1.2.0 build 129 mpv 033.0 and 0.32.0

Expected behavior:
I should be able to double click repeatedly into the window of a video playing, causing the video to go into full screen, then back down to window, then full screen, then window repeatedly.

Actual behavior:

The enlarge to full screen / reduce to window size only happens once each. After this time, I must quit the program to get this behavior back.

Steps to reproduce:

On a

• MPV does not have this problem.

How often does this happen?

It seems to happen all the time if I have Use Legacy Full Screen on on my M1 Mac Mini. It doesn't happen on my Intel iMac nor my Macbook Pro M1X with the same settings.
