Graphical glitches in SCBI - Pink Pixelated Frozen Screen

We're talking about an old game originally designed for Android which has never been 100% matched to iOS, integrated, but not matched. 

Due to Apple's design and strict use of RAM and background apps, every update becomes a hassle for trouble shooting.

What I am finding (especially, with A-Series devices) the game is GPU heavy and Apple devices are not forgiving.

Due to Apple's design and the game's design your device is bottlenecking faster than Android or M-Series (tablets and Mac).

So, if you have done everything I've suggested so far

1. Game mode off
2. Background Apps refresh disabled
3. Have up to 15 GB of storage available 
4. Offload/reinstall 
5. Force restart... This will reset memory whereas a shutdown keeps working memory where it's at.

Finally, any adjustments to display/resolution, brightness and turning off any battery optimizers/low power mode settings would be beneficial.
