The mouse and controller point-plus-circle cursors in HMD display mode could do with a few improvements:
They should operate outside the bounds of the HMD display box. For example, I cannot click on the “power” button shown in the picture.
It is implemented as a billboard overlay and the cursor position in the picture shows the closest that a cursor can get to it.
They should appear at the depth of the object that they’re hovering over. This per the Oculus Best Practices Guide: “otherwise, it can appear as a doubled image when it is not at the plane of depth on which the eyes are converged”. Currently they appear on the HUD surface.
