Missing "Full Screen Mode" toggle in app settings

[P1XEL07]

I recently flashed the HyperOS 2 ROM (the TOPAZ variant) on my Redmi Note 12 4G Tapas, and so far I had no problems, well except for one. After this update, I noticed that when I get into an individual app settings, the "Full Screen Mode" toggle has gone missing. Am I missing something here? I've been looking in different forums for hours and so far, I found nothing.
I should mention that I have HyperCeiler installed, but even after resetting all the options, that toggle is still missing.

I don't have it as well, stock HyperOs 2 on fuxi, I don't know if it's Xiaomi 's decision to remove it or Xiaomi.eu's but it was pretty good when running older games

That's odd, I see no point in removing this option. A lot of old Android apps kinda need it to display correctly and not limit themselves on a 16:9 aspect ratio. I hope this is actually a bug and not an actual decision taken by Xiaomi or Xiaomi.eu.
