Feels like plane translate's up and down when tilting head (up or down) in cockpit view with Hp reverbe g2

[DT19698255]

Recently I have the same with the Reverb G2. But it is not only up and down, also sidewards. Or back and forward. Not only by moving head.

View in vr shifts abruptly

Since yesterday in the cockpit the view in vr (HP Reverb G2) shifts abruptly. It feels that the position changes forward or backward every few seconds. The onliest thing that I have changes was updating the WMR software. Anybody else has this issues?
