Ui scaling porblem?

Hi i have a weird issue where my UI has some "unused" space behind menu options. When I scale the UI inside the options panel those marked parts will not change and I believe that the bottom box for your dimensions contains way more info and is bigger also. What I can remember is that I used a custom scale of 105% in windows and changed that back to 100%....but Iam not entirely sure when that phenomenon started tbh
Any ideas?
