Change OVROverlay shape at runtime (GO/QUEST)

Hello,

Is it possible to change the OVROverlay Shape at runtime?
I logged the currentShape in game and it changes correctly, but the actual visual image stays unchanged.

I used this to change between quad and cylinder:
overlayComponent.currentOverlayShape = OVROverlay.OverlayShape.Quad;
overlayComponent.currentOverlayShape = OVROverlay.OverlayShape.Cylinder;

Any ideas or is it not possible at all?

Best regards,
