Issue: Icon still shows on fullscreen Youtube videos even after apparently being fixed

Basically what the thread title says. Even though I’ve checked posts here that suggest this was fixed, the Min Vid icon still shows for full screen on Youtube even when I’m not moving my mouse.

Is anyone else having this issue and does anybody know a potential cause and maybe also a fix?

I have the problem as well and is interested also by a fix.
