RhinoRender: "Zoom In" Button scrolls the image diagonally away

When hitting “Zoom In” while viewing an image rendered by the new “Rhino Render” engine, the image just moves off the viewport (top-right direction) a little by every click.

“Zoom Out” and all the other Zoom Buttons work fine.

I see this on my machine as well. Logged in MR-1566. Thanks for reporting it.
