I can't see my teammates' health bars

When I’m playing Support and the game mode is the type that has multiple rounds, I have a bug that prevents me from seeing my teammates’ health bars. The first round is perfectly normal, but by the second round, the bug kicks in. It’s weird. I can tell if they are critical, and if they are behind a wall, their outlines change color if they are below full health, but the health bars themselves are invisible. It goes back to normal if I switch characters (so if I want to play the same character, I have to switch, then switch again), but I shouldn’t have to do that in the first place.

Has anyone else experienced this? No one else I’ve spoken to has even heard of this bug, so it seems to be only me. I assume it’s not a common problem because I’ve had this issue for over a year now and it hasn’t been fixed.
