Bug: after the 'cut' operation, we have a valid shape (checked using checkshape). But if you look through the viewer, the shape looks not valid.
Possible causes: incorrect rendering, incorrect validation, incorrect boolean operation.

Note: the input is valid.
Note: please, after finding out the reason, change the category of the task.
