to repdoduce:load image (tested only with one with wierd orientation, if needed i can provoide some)
start segmentation with 3d interpolation

after segmenting two slices, press "suggest a plane" button.

problem 1: suggested shown plane might be rendered black
(scrolling up+down resolves this)
problem 2: the segmentation performed on the rotated planes does not appear where it was drawn but with an offest at another place.

BUT: segmentation on manually rotated planes works as expected,
furthermore, of a plane is suggested, and the planes are afterwards rotated manually a little bit, the segmentation works correctly afterwars for this plane.

problem _might_ be, that the automatic rotation is not fully performed or an update is missing, since all pieces it uses work when used manually.
