Lot to digest, deserves a more of a response, but for now change the SteamVR to the beta client. I had issues with the Index and white flashing spots, solved it by swapping over, worth a try.
lol I solved the white spots by ordering another hmd from (insert name here) and it came an hour ago, no more flashing white spots, the 'old' hmd is being returned.Could be a brain tumour.
