I just got the headset unboxed and I downloaded Robo Recall. I started playing, but after about 15 minutes the game kicks me out to the oculus home repeatedly.
I think it is a tracking issue. The screen was still before it happening.
I don't know...it started happening to me last night as well, and I was playing Space Pirate Trainer, with my shield and gun in front of me. It's the first time I've experienced it with my Quest, though I've read others have similar issues. It kicks me to the 'exit/resume' screen, and at least once, it just jumped me right back in on it's own. This was after about an hour's worth of playing though, and I'm thinking it might be overheating. It didn't do it while playing Space Pirate Trainer through Virtual Desktop and SteamVR, with the pc doing all the rendering.
