It's not yet solved, but I could narrow it down to what system setting
triggers it:

In the settings dialog for "Screen Resolution", there is an option
labelled "Make text and other items larger or smaller", which on my
desktop was set to 125%.

Java up to 8 totally ignored that setting.
Java 11 tries to follow it (which is arguably an improvement), but
   does so in a somewhat broken way.
