Okay I've been on multiple threads and tried pretty much every combination of the UI scaling and still the interface is way too big (the swatch pallette in particular is so so wrong... -- you can see the size it should be when placed alongside the one in Indesign. is this something Adobe are working on, or is there something I'm missing?
Cheers in advance,
It would help us to help you if you provided more information
What OS and PS versions do you have, system specs would help as well.
The more info you provide the easier it is for us to help
