System and IINA version:

• macOS: Version 13.1 (22C65)
• IINA: 1.3.1 Build 133

Expected behavior:
After resuming playback of a video file with secondary click (two finger click by default on macbook) the UI & cursor should become invisible after a short period of time.

Actual behavior:
After resuming playback of a video file with secondary click the UI becomes invisible but the cursor remains visible.

Steps to reproduce:

• Open a video file
• Pause the video
• Wait a couple seconds
• Resume the playback using secondary click on the touchpad

Note: I think you need to wait a couple seconds otherwise the system will make the cursor go invisible based on the action before that…?

I don't know what MPV is so I can't say whether it's a bug of MPV.

How often does this happen?
Consistently. As long as you wait a couple seconds.
