Since the new update I've been having some issues. Apparently it added a VR Desktop which is considered as a 4k monitor by Windows. The problem is that it's having quite an impact on my performance, also it's really annoying when pressing printscreen or opening the SteamVR overlay, since most of it is just empty area. I managed to disable it temporarily by disabling one of the experimental features, but all of a sudden it's back and I don't know how to get rid of it.
I'm also having an issue where the Oculus app immediately starts up again after I close it, it's not as bad but it's a bit annoying as well.
