Thank you for the information!
For the mouse issue, it is how it is designed and currently I do not think I can find a way to enable both mouse and vive controller input, and I myself hate the exclusive vive input...
But yes, the headset issue is definitely serious. Would you please try to (this seems fun but I am not making fun of you:) move backwards to see if the headset becomes totally white. If so, please calibrate your device because before I have kind of same problem as you described. And if calibration do no help, I think I met a huge problem..
And again, thank you for the information and this post. I have been so worried because no one ever post anything. And apologetically, I am a student and kind of busy these days. I will be free and continue developing this game after maybe Nov. 15.
