Black bars when attempting to play fullscreen on OnePlus 13R

Hey there,

So i needed to play my very authorized copy of Emerald in Pizza Boy A emulator and that i see this black bar each time when taking part in. Different apps and the homescreen are all fullscreen together with the digicam notch and don't have this black bar. I attempted the settings concerning the digicam notch however nothing adjustments. I exploit the 13R.

Does anybody else appear to have the identical drawback and/or answer?

Thanks
