vertical drift
Works amazingly well with xrdesktop (tested with its gnome-extension), even in 3D mode! Only issue is vertical drift to the left. Monado-service gives a lot of "Frame late" warnings.

Same occurs with hello_xr. This is the only issue left which blocks use of the glasses for something more than a glorified second monitor.
