I do get some warnings. Font Book shows “52 minor problems were found”. Most are “Duplicate fonts”, but there are also real warnings like “name table structure”.

To clear these warnings, I moved all font files in ~/Library/Fonts elsewhere, but the problem still persists, though the delay for the testing text is much shorter (about 5s now).
