Setting the video quality through the script settings breaks the auto-switching quality when switching to full screen mode.
Switching for me is provided by the Enhancer for YouTube™ extension.

Perhaps you should add your auto-switching quality, i.e. different quality for normal mode and full screen mode. As an option, also for theater mode.

From what I understood from extention's description, it can set quality itself. So I suggest you to use extention's functionality in this case and leave "default" in script settings.

Regarding implementing autowsitching: I curently don't consider it feasible to implement.

I do use the extension, and your script breaks its function in that regard. That's why I suggested you add your own function for this, if you can't make it so the script doesn't break extension functions.

I'm not an idiot, I didn't originally have this feature enabled in your script. Then I turned it on, everything remains the same - the expansion feature stops working with any settings in your script, and works again when you turn it off.

@wvxwxvw Does extention broken even when script set to "Auto (default)" setting?

Also, do you have "Simplify fullscreen" enabled?

Yes.

Yes.

This "Simplify fullscreen" is to blame. Sorry.
Issue resolved.
