IMPORTANT
There was an issue with the keybinds. We've pushed an update but it didn't completely solve the issue. You need to go into settings -> controls -> click reset -> click apply and then it should work fine. Sorry for the inconvenience. We're trying to solve this as quick as we can.
Dying while on the pause menu will keep the pause menu on top. You can still play it if you press pause key and then "Resume", although with a dead widget on top. You have to rejoin the server to make it go away.
After a match ends, pressing Menu->Settings->Back will get you the pause menu and the only result from that is a black screen. The only way to solve it is to Alt+F4 and start the game again.
There's a bug where your cursor will stay on the screen and block aim control. You have to wait for someone to kill you and then you'll get to the respawn screen without any respawn button. You need to press your respawn hotkey to respawn (default is Z) and then you should have normal aim control again.
Playing in aspect ratios other than 16:9 breaks some things. If you can, force that aspect ratio on your screen.
