This has been a problem for ~6 months and still no real response for the developers. Still can’t see the attack overlays for aiming, sprays, or AOE indicators like bombs like D.Va’s self destruct. This makes the game extremely difficult for new players. If you are on an M1 Mac, go to a map that has no floor on the edges, The layer is still there, just hidden on normal map terrain.
Please Developers! Fix this!
