As the title says ‘Sprite Sort Point’ seems to be broken in 2021, the sprites are working as expected in 2020, but when updating to 2021 they start blinking when overlapping (like they can’t figure out who should be over who), but it is still set to “Sprite Sort Point: Pivot” and the Pivot is correct (they always blink no matter where the pivot is)
this seems to solve the issue for me
