Handles.DrawCamera - flipped normals?

So i'm experiencing something weird using the Handles.DrawCamera. When i make my camera render a game object using the Handles.DrawCamera to my editor window I seem to get flipped normals like seen on the screen. (Screen is taken from the editor window.)

When looking at the game view there's nothing wrong.

Have anyone experienced this before, and possibly know what's causing it?

 

I'm gonna bring up all topics on this subject. This is a known issue since that have been submitted as a bug many years ago.
