Just upgraded to 14.1, huge green square in 3D view

[Storken]

Hello. Long time lurker, first time poster.

Tried out 14.1. Seems ok, but I'm having a weird view in 3D view. In 2D it is ok. It seems like the board redefine have been changed slightly. Now there probably is some setup in some hard to find menu, has anyone seen similar to the attached screenshot?

(I vaguely remember something similar in 13 - early on. Someone disabled something and everything was as it should be)

Happy holidays

After a restart of the program, this problem is gone. Weird. 

Anyhow
