terminal output for "solve" in Ubuntu displays huge list of fonts it can't find

[dandrake]

I'm on Ubuntu (25.04) and just tried "puzzle solve". It works, but when displaying the graphical windows, it outputs pages and pages of all the fonts it tried to find but couldn't.

Draw the AST and evaluation results for the following expression:

    0 + 1 + "2" + 3 + 4

Things to double-check in your solution:

  - Did you indicate the distinction between ints and Strings?
  - Are your left/right branches correct?

It might be something weird with my terminal, or my Java install, or something else? But I have a pretty standard install and I'm sure there's some suitable font somewhere available?

(The resulting windows, though, look perfectly fine.)

Just FYI.
