MacOS: Improper sizes of the windows and graphs

[levonamatuni]

The main window (either minimum or the full-screen state) is overly big on a regular 13'' screen Macbook. Moreover, the 'LCA results' graphs scale down one after another (recorded on a screenshot).

Thanks!

Hey, sorry for not getting back to you quickly.

I currently can't see a good way of handling this problem as it needs to be fixed everywhere in the code, touching almost all parts of the code where a widget is used.
