[vtkusers] Image "swimming" with vtkImagePlaneWidget?

[Cory Quammen]

Hi all,

I'm using vtkImagePlaneWidget in an application and I noticed a
problem when rotating the widget. The image appears to "swim" relative
to the widget plane when rotating the plane, jumping around in
seemingly random directions rather than varying smoothly as the plane
is rotated. In-plane and out-of-plane translation seems fine, as does
resizing the plane. I see this problem on both a Mac with an AMD
graphics card and a Windows laptop with an NVIDIA GPU.

Has anyone else seen this behavior?

Thanks,
Cory
