Size of Pop-Ups on UHD Screen

I have a Dell XPS 15 with a UHD display and Processing 3.5.3. Pop-up windows are very small. Does anyone have a solution to this problem?

I am a new user, so I can only supply one picture below. The problem happens at startup, for the color selector, the movie maker, and perhaps other functions. I’ve been getting by from the memory of how Processing worked on my lower resolution display.
