320x240 registration on Astra Mini

Registration appears to be wildly off in 320x240.

Steps to reproduce:

Download Astra SDK 2.0.16 Linux 64-bit
Edit SimpleStreamViewer-SFML to change 640x480 to 320x240 on all streams
Run SimpleStreamViewer-SFML
Press “O” to toggle depth overlay
The RGB image is several pixels too far up and too far right (20-40px)

Can this be fixed?
