--- Comment #9 from Ahab Greybeard <ahab.greybe...@hotmail.co.uk> --- With the 4.2.6 appimage on Linux, I don't have that offeset after Undo. I do see the transient selection offset as Trim is being performed (especially now I'm replicating your image and using a small selection). The transient offset appears to be equal to the initial selection offset from the top left corner, as you noted. Even with a large selection, I don't see any transient shift in the image layer itself. I've tried it with Image Preview on/off and Graphics Acceleration on/off and that made no difference. Does that make any difference for you?
