Could you please try them and confirm the issue is fixed in your project?

Hi Josh, I'm investigating the issue about the drop down not moving along with the headset and have one question just to confirm.
Is it possible that the panel containing the ComboBox is not placed in a static position in the 3D world, it is moved to be in front of the camera instead?
Because moving the camera shouldn't affect by default the position of the ComboBox and its drop down in the 3D world, only if the ComboBox is moved is when this issue could be happening.

I generated new libraries with a patch for for popups that target 3D moving elements, could you give it a try?
