Ideas
I'm on PC/Steam and im playing with the Astro C40 Pad. It happens when im about to aim with the left trigger, boom it opens the scoreboard. This Bug is annoying, you can't aim no more for the rest of the map. Only "fix" is, close the game and restart it. I've repaired the data but nothing changes. This is one Bug you can't play with seriously
are you playing in full screen? every now ands then I get the bug where the mouse cursor is stuck on my screen. I wonder if it is related. happened in bfv too with a totally diff machine lol. I've only gotten scoreboard stuck on my screen once and other people on team did too, but it was when i was looking at the scoreboard. it didn't happen out of nowhere, but it never went off. but if thats all it is brother set a diff key. it hasn't happened to me again and I wonder if it was because I occasionally play in windowed mode while I also watch a video on an extended screen. and it just makes it easier to jump between them. but i've been on fullscreen now.
