There is a minor bug in
cameraViewport extension causing right mouse button menu to popup when it shouldn’t. More specifically, it appears when user is finishing navigation with right mouse button in viewport - dragging the mouse towards left or bottom. Based on this behavior I have changed the line 313 (to use absolute values) in CameraExt:
# flag that the camera was moved a little if abs(deltaU) > 0.001 or abs(deltaV) > 0.001: self.didCameraMove = True;
This way popup doesn’t appear when navigating the viewport.
