There's a grapics bugs in the Tranquil Temple showing small black square in the floor
There's should no that in the floor
Mali-450
Android 5.1
Octacore CPU
PPSSPP 1.5.4-991
Look at the floor there's are small black square shape.

try lowering the resolution to 1xpsp or 2 psp
This is 1xPSP resolution @SamueldeSena
These squares look very similar to those in https://github.com/hrydgard/ppsspp/issues/11019. Funny, that game had ice too!
I feel like this was some Mali driver bug, and seen in other games like Monster Hunter even.
I vaguely recall it being depth related? It might help to try toggling HighQualityDepth in ppsspp.ini if so (there is no UI for this setting.)

No changes happen :(
I change the HighQualityDepth number from the default is 1 so I try 0,2 & 3 the black square still there.
*Sorry for my bad english
In PPSSPP 1.6.2 showing a grey color in the right side when immersive mode is OFF

only happen during introduction movie
The graphics bugs it's not only showing in Tranquil Temple and I think it's the same issue as #7218 because it's only happen in Mali-400 & Mali-450 as I tested it on Mali-T720 the graphics bugs didn't show up.
So I will close this issue :)
