"wavy " objects , oculus 2?

Hello

I am having difficulty solving a problem with objects appearing to follow my head position vertically when I move my head. I get the feeling that objects move up or down by 10 or 20 cm as I look around. However, in SteamVR home everything remains stable when I look around.

I assume this is not an issue with my headset itself. Does anyone know what software settings could be impacting this bug? Any suggestions on fixes would be appreciated.
