Did you restart the game fully? That usually fixes that problem! It's a very rare bug, that only occured once during our extensive game testing sessions
No I hadn't, but now that I have it's even worse, escpecially on higher qualities. I even turned pixelated and glitched back to spectating. And on lower qualities it still doesn't work. We were thrown out of the barrier, and fell down into the void and our screen would change to the other person's screen or none.
It could be caused by your Computer, now that you mention the quality settings. We will look into it, however we only had the second screen bug so far but not the other things, it's really odd!
