As a followup after checking pd-gui.tcl, the default font is Deja Vu Sans Mono in the find_default_font method, followed buy Bitstream Vera Sands Mono, Inconsolata, etc.The problem is that this method is only called in startup if tk 8.5 is being used, as it is right now, the precompiled Vanilla is built using the older tk 8.4 Wish app so the font finding method is not used.Alex, can you try one of my vanilla builds that uses tk 8.6? http://docs.danomatika.com/pdbuilds/ Since you have Deja Vu installed on the system, it should be picked up automatically (in theory).
