Registered to say that I also have this issue. After time, I find my image rotating to the right as shown in the image in the OP. If I set my psvr on the floor for example, and calibrate, I can watch the third coordinate reading slowly climb as if it were slowly tilting. Sometimes it’s worse than others, but I’ve tried it on a few surfaces thinking that maybe that’s what the issue was. I’d like a button that would reset this rotation to the “origin” but I’m not sure if that’s as simple as it is for the button that already resets rotation.
As an interesting side note, I’ve had my psvr on the floor and trinus running as I’ve typed this. The third reading has gone from about 0.80 to -0.12, so it seems it also switches between going “up” in value and going “down”.
Otherwise, everything seems to be running great. Slight left drift, but I know that’s standard, even when I run it on the PS4. Don’t ever seem to have this other issue, however.
