Steps to reproduce
  1. Launch VRChat in VR mode
  2. Use a taller than average avatar
  3. Deploy a drone
  4. Enable drone FPV
  5. Switch to a shorter than average avatar
  6. Enable drone FPV once again
Actual result:
The FPV screen scales differently depending on the size of your avatar. The largest possible scaling option in the drone's settings is still very small for short avatars.
Expected result:
The drone FPV screen should be the same size regardless of what avatar the player is using.
