I'm creating 2 BPP script process icons - one for 1x1 binning and one for 2x2 binning. I believe this is necessary because I've started using Overscan and the geometry/parameters are different depending on the binning.
The bug seems to be that in the "Overscan parameters" window of the "Bias" tab, while the "Image region" parameters are correct and different in each of the 2 process icons, the "Source region" and "Target region" don't seem to be stored in the process icon, but rather remember the previous BPP overscan parameters.
eg
- Set up a BPP process icon BPP_1x1_template with the Overscan parameters in first screenshot
- Set up another process icon BPP_2x2_template with parameters in the second screenshot
- Open up the first process icon for 1x1 binning and the source and target regions carried over from the 2x2 one. See third screenshot. Change them to the correct 1x1 process icon settings, and the 2x2 one is now incorrect.
