Hey,

I don't know or this is a bug or a setting but the screen proportions are overlaping the menu.
I made a screenshot

Gr.

It's screen proportions, if you look closely, you can see another edge on the edge of the app window colored red.

the Editor GUI is inside the application window, therefore its part of the screen proportions.

But it overlaps my editor menu, so i cant click on the view or editor options anymore without moving the objects..

I think that it's correct because space of menu is also space of whole window and when you'll test your gui in game it will be correctly drawn on the corner of your window. Otherwise you will have it in wrong place.

From the other hand you're right that in this situation using menu buttons is a little bit hard
