536f1 Cardboard world canvas issues in editor?

So upgraded unity from 534f1 to 536f1..

In the editor there seems to be some problem with moving world space canvases, see the gifs below:
(world canvas is child of CardboardMain, and if CardboardMain moves, it causes issues)

with 534f1 (no worldcanvas ghosting issues)

with 536f1 (canvas "trail")
