ALT+Z

It should be automatically adjusting when you hit Alt+Z can you check if you have LUA error enabled and there are none being generated?

I check the box to show me the lua errors, but there are no lua error by hit ALT+Z

Maybe my resolution causes problems? I play on 1920x1080

 

UPDATE:

I just disabled the Viewport. It fixed my problem.

ya that is the viewport and it should be auto adjusting. I will try to make some tweaks and see if i can find anything.
