Each second frame in ScanImage is acquired from the other direction. Consequently, we arrive at mirrored frames with the multiscaler. The even frames look like fliplr mirrors of the odd frames. We should fix that.
This seems to be a problem we have created ourselves with the multiscaler code under ImageGeneratorHist3
I've commented it out and the issue is seemingly resolved.
