I was just testing out some applications on my Go, and I noticed a new bug. The bug occurs while playing an application and pressing the Oculus button on the controller to pause the game and bring up the "quit/resume" Oculus menu, then clicking on "resume" to go back into the game, upon resuming the framerate in the game begins stuttering. Upon subsequent pause/resume actions, the app begins to stutter harder and harder, running at a very low framerate. At some point after multiple pause/resume actions, upon resuming, the application is back to running at what appears to be smooth framerates. However, continuing to pause and resume using the Oculus hardware pause button, brings the poor framerate and stuttering back into play.
I tested this on multiple applications on multiple headsets and got the same result every single time.
Oculus Go version is: 188.8.131.52.626.168186885
