It is not consistent and purelly random. Some times works properly:
home button -> right pannel -> popup with screenshot function
Other times it acts like teasing me with no reason, and disapears before can click the screenshot button.
Also is annoying the 5 seconds time out. Should acts like in Quest, autoquit the HUD.
I keep looking for the "bug". I may need to point the left hand laser towards my back so it doesn't happen.
