Unfortunately, I'm still unable to reproduce it on the native screen of my laptop. Previously I had used 175%, until I found my eyes hurt after a full working day. Even then I had no cropped dialog issue. I tried with 125% and 225%, but the dialog still scales nicely, even if I start Archicad from scratch, or adjusting the scaling while AC is running.
I still think that it somehow relates to external display. I remembered coming across this issue once with an external 4K monitor, but it was long ago that I can't remember which AC version it was.
