Attempting to use the camera rotation button, such as middle mouse or Z, causes the camera to bottom out and then the game and a lot of the rest of my desktop to freeze for a couple minutes. After the freeze ends the game is left with menu glitches and a camera I can't put back into normal place until I restart it. I'm running Arch Linux up-to-date as of writing, my processor is an i3-6100, and my gpu is a GTX 950. I use Nvidia's proprietary graphics driver for linux.
