+Version 2.9.4p1 contains a fix for font selection.  If you are upgrading from 
an
+older version and fonts are still not loading properly, e.g. the "Add
+Object->Text" or "Add Negative Space->Text" doesn't show a font name, try
+deleting "~/.config/PrusaSlicer/cache/fonts.cereal" and restarting PrusaSlicer.

Since that's all that changed, this still has my OK. Thanks.
