How can I stop Adobe software from scaling up? The UI is too magnified.

I don't want to scale up everything (ie. change Windows scaling globally, because it's a 15" laptop screen and it's 4K) like many people, I want to shrink everything to actual size when I'm using busy user interfaces like Adobe Premiere, otherwise I'm mostly wasting my 4K screen resolution!

• I've tried the .manifest file with registry hack.
• I've tried changing the Compatibility option in the shortcut and on the .exe itself.

Has something changed in the latest version of Windows/ Premiere?

Thanks for any ideas!
