The same poster has problems with the Delphi 11 font size, so probably plays with individual settings in "ease of access" or whatever instead of only increasing the scale. If complaining it would be helpful to add the specifics. Anyway, Windows is known not to handle this always nicely and depends way too much on developers involvement. I suggest to depend only on the scale factor (which I have @125% for a 4k screen)... if you don't want too much frustration.
anyway, with or without spacing, that dialog is crowded 😉
