In actually the last few Weeks me and my friends who use a Oculus Rift CV1 have experienced Freezes all around VRChat. We call it a freeze but it just really stops video from being shown to either the HMD or when you take the Headset off, on the Desktop. You can still fully hear and interact with anything else in VRChat but you're basically a blind man. I don't know how to recreate it since it's seemingly random but the issue is definitely there and definitely ruining my experience and every other CV1 User with VRChat.
This issue apparently only concerns CV1 Players as mentioned earlier.
