The Steadycam is not affected by ScreenCamera.DepthTextureMode nor PhotoCamera.DepthTextureMode. It ends up using the same depth texture that was rendered for the screen or photo camera (whichever rendered last), which is invalid and noticeably displaced.

Same thing as this canny, but for the Steadycam vs cameras on avatars (which is ultimately fundamentally different): https://vrchat.canny.io/feature-requests/p/vrccamerasettings-depthtexturemode-doesnt-affect-avatar-cameras
