vtkResliceCursorWidget issue

Hi, can you give me any hint about strange vtkResliceCursorWidget behavior?
I've written two videos. The first one was written when reslice mode set to
oblique. I scroll throught slices in the left top window and image in the
right and in the left bottom window constantly changing. But the slice
doesn't changing for those views. And when the resclice cursor widget is on
the top part of image the top border of image changing. And then it's on the
bottom part - the bottom border of images changing.

And the second video has written on the same data and the same situation.
But reslice mode set to axis aligned. The right and the left botom images
don't changing during scroll in the left top window.

What the reason can be for such behavior?
I'm using VTK 8.2.0
