Hi Gabe,
ok, i tried to record that. I started with stitching pictures to a panorama. Then i klick on the crop tool. As you see, the mode is "uneingeschränkt" (must be "unconstrained" in english). This is default.
First i klick on "crop to opague", because that is the minimum area i want to get as result. Usually i choose the inpainting-function next and then i try to expand the grid to get more of the picture - including transparent areas. But here is the problem. Even with mode "uneingeschränkt" selected by default the grid behaves like original size, if i pull the markers.
But i found out something new: If i change the mode to any other mode and switch back to "uneingeschränkt" it works as it should. But if i klick on "crop to opague" again, it behaves as original size like before. You see the mode in the video. Seems as if the Button "crop to opague" resets the mode to "original size" but still displays "unconstrained".
Just testet the other button "an begrenzung zuschneiden". Same effect.
