Hello Andrew, apologies for the delay

I just wanna make sure that I understand you correct here so there is no confusion later:
You're aware that the red outline in the preview is the current canvas and the white rectangle is the resulting canvas. This works as intended (I expected them to be the other way around at first, to be honest.)

But your expectation is that positive x-offsets should move result canvas to the right relative to the current canvas, and a negative offset should move it to the left, yes? That I agree with, because that seems to align better to how the rest of Krita deals with position.
