You can download previous versions from 515 here: https://www.byond.com/download/build/515/
It uses webservices2 instead of internet explorer 11 for browser elements. Thats the cause or else its some other change to UI screen_loc positioning. either way you should figure out what the issue is and fix it because old BYOND vers are getting deprecated fast.

I do have webservices2 but my UI seem to be way too big and I have no idea what is the problem.

There seems to be an issue with having a DPI greater than 100% on your Windows. Try seeing the problem persists if you go to 1x.

Changing from 150% to 100% pretty much break everything but this might be because I am on laptop.
