Steps to reproduce the problem:
(the game is paid so I can provide you with access to Google Play Internal Testing if you give me your email)
-Select any hero
-Click "Play" button on the bottom of the screen to enter the game
-In the game, Select "Options" at the top-right on the screen
-In the graphics section turn on "Temporal Anti-Aliasing"
-The graphics become corrupt
But on ARM Mali-G76, Huawei Mate 20 X, everything works fine.
So the ARM Mali-G78 must have some bug.
I'm using OpenGL ES 3
Can you please investigate?
Thanks Pete, I've sent.
