i use a DELL P2715Q Screen as my main monitor for my MacBook Pro 15" 2017.
The Monitor is scaled to 3840*2160 px
When i start invison Studio on the external screen and resize the window to Fullscreen invision studio misaligns the select boxes from the elements.... bit hard to describe so i put some screenshots up.
Everything works fine on the internal screen
here are some screenshots https://imgur.com/a/V9b4IkU
