window drifting when lying down

[122014860]

Hello I'm trying to show a virtual desktop above me when I lie on my bed. I found the window keeps starting to drift parallel to the window every 5 minutes or so. Particularly, when I put this window nearly parallel to my floor, the window could suddenly start moving in the horizontal direction for several seconds. The movement could be ~30cm or so.
Later I tried side lying, in this case, the window is nearly in vertical direction (perpendicular to my floor) but nearly 90 degree rotated. This time I found the window could drift in the similar timescale but the movement is nearly negligible.
At first I thought there are some tracking issue with my Huawei 6Dof VR glass, but as I compared to the VR environment such as SteamVR Home, I am pretty sure that only OVR window is drifting while the SteamVR Home holds still.
I am wondering if this is just some setting issue, or there is some solution to this?

Well that sure sounds interesting, not sure I've heard of this before. :)

I know a similar issue can happen on Oculus devices due to their inside-out tracking system gradually adjusting over time, whereas the same issue doesn't exist with an outside-in system like Lighthouses, but you did mention you'd looked into this.

Maybe you could grab a video of this happening? But it is very likely the space is moving more-so than the overlay itself if Edit Mode is turned off on the wristwatch. :o

sorry bro. i rechecked it and i think it's a tracking issue. maybe my roof top is too high (~3m). The VR environment is also moving but I cannot notice it when it's too far from my sight
