[PD] font issues - once again ...

[oliver]

hi !

i am aware, that font (compatibility) issues have been discussed here 
quite often, but i'd like to open it once again ...

recently when i tried to check a couple of my abstractions for 
cross-platform compatibility, i discovered a huge difference in size 
when the default font (DejaVu Sans Mono) was used on either windows/osx 
and linux.

But "DejaVu Sans Mono" on Linux (Ubuntu 19.04) has a much larger spacing 
than on both other platroms, making text designs in PD patches 
incredibly difficult to be cross-platform. i'm not talking "not 100% 
precise", it's way more than that, as you can see on the screenhot i 
made with the attached patch on 3 different systems. only on linux the 
text is way too long for the background canvas and becomes invisible 
(because it's white ...)

(or see the screenshots here:)

Some questions:

1.) Do other Linux users have the same font experience, or is my distro 
messed up ?
2.) I installed 3 fairly recent PD versions on each system (0.50 in 
win/osx, 0.49 on ubuntu via apt-get). why do they all use different TK 
versions ?
3.) why is the windows default font-weight bold ? it looks ... well ... 
fuzzy to me ... (though it's no big deal as i can change it in the 
preferences - but what's the design decision here ?)
4.) why "times" ? ;-)


(i won't even bring up the subject that the three standard PD fonts 
(DejaVu Sans Mono, Helvetica, Times) all look quite different on either 
platform, but since the spacing is more or less correct - safe for 
"times" which i never use - i don't really mind.)


thanks for help or clarifications

best

oliver
