Using 11.1
See pic
After ALT+right-clicking on one of the coordinate output pins of the renderer (second from left), the renderer window detached from the renderer node. Didn’t find a way, to get it back to the right position. Was boxed view. Windowing or fullscreening didn’t help but copy all nodes and insert them into a new patch worked. But after ALT+RC on the same pin, the same thing happend.
After ALT+3 the patch and restoring it, all was correct again.
