Cutline becomes invisible when moving the camera

Problem: Outside of the normal view the cutedge is not painted. But the cuting logic still works.

Reproduce: Use the mouse wheel to scroll the view a little bit to the side Try using the cutedge

I know that it has to do something with the boundingRect function of the QDMCutLine. When replacing it with

return QRectF(-32000, -32000, 64000, 64000)

everything works.
