After an update 3 months ago, when I want to change the color of a text highlight or of a sticky note, the color choice box has become tiny and difficult to use (see attached screenshot).
I use a high resolution screen (3840 x 2160 px) and this tiny box looks like an object which hasn't been re-sized for my screen
Note: my version of Acrobat Pro is up to date and I use the "old" interface
