Correct answer sanjaykr

With 18.1 update of Adobe illustrator,  we have added an UI option under preferences > User interface section to either turn off scaling completely or allow users to snap to lower or higher supported scale factor. Since Ai only supports 100%, 150% and 200% scale factors, users can choose to snap to 100% or 150% when his/her OS ui scale is between 100% to 150%. E.g. for 125% users can select lower supported scale factor to snap Ai ui to 100% and higher supported scale factor to snap to 150%. Similarly for OS ui scale 175%, users can snap AI's ui scale to 150% or 200%.

If you have defined the environment variable UI_SCALE_FACTOR=1, Then this preference will not work.

HUGE flaw, how does this just slip by? "Illustrator only supports UI scaling of 125%, 150%, and 200%". How limiting. And disappointing...

    Sheesh, after the update I wasted a load of time trying to find out why everything was massive again! After a while, I came back here, to find Sanjay's explanation. What a ball ache! Right, so now the UI scale factor variable causes the problem and needs to be deleted. Cool.

    Despite my unnecessary sarcasm, cheers for the update Sanjay

      100% is too small and 150% is too big. How to use in 125%  like before?

      Changing the Windows scaling causes other problems which of course is only a temporary fix. This is the first real problem I have ever had with Illustrator.  I just have to ignore the giant text cursors as adding the environment variable caused other problem's.  AI is the problem and I am waiting for a fix for this nonsense.  First real nasty problem I have ever had with AI.  Going back previous version.

      Using the UI Scale works, but rather disappointing that Adobe tries to introduce something new but eventually break the entire freaking thing. UI Scale should be toggle-able man...

        Thank you! I changed my setting to 124% and it worked like a charm. I don't have the problem on my desktop computer, just my laptop, and it was driving me nuts in Illustrator and InDesign. All back to normal now.
