ORIGINAL: As of 18.104.22.168, the mouse cursor in VR no longer moves reliably in the cockpit unless it is hovering over a toolbar panel window or when in the menu overlay, making it impossible to use cockpit controls with the mouse. I’m officially grounded.
EDIT: Tracked it down. Turns out that when using the excellent Kodiak 100 throttle quadrant workarounds posted by SimHanger, as of 22.214.171.124 the propeller and condition lever workarounds interfere with the VR mouse when the levers are below their detentes.
It appears that keeping some controller commands “depressed” interferes with VR mouse performance now under certain circumstances.
