no time now but you can do this instead of the lmt_text:

     draw lmt_outline [
         text = "\bf\strut #1",
         kind = "fillup",
         fillcolor = "white",
         rulethickness = rulesize,
     ];

(maybe spaces creep in due to loading font files / setups or so)

Thank you!
Yes, this works, and with rulethickness=0 it even looks like I wanted it to.

Good idea, makes sense for big text – my captions are only 8pt, there 10 
layers are already a lot, and the randomness doesn’t make a difference.

For titles, it would be nice to apply lmt_poisson to arbitrary paths.

I wonder what’s possible if we don’t _draw_ lmt_outline but use it as a 
base for more fun…

Hraban (and others),

You got me thinking so I added this code to end of your code as a bit of 
fun. It's code from the luametafun manual to which I added two and a 
half lines.

Best Wishes

Keith

That’s funny.
I replaced the text by \TeX and published it here: 
https://fosstodon.org/@context/110684919994406565

But is it possible to fill a path (e.g. an lmt_outline) with a 
lmt_poisson pattern?

Here's something to get you and Keith starting:

\startMPpage
picture p ; p := lmt_outline [
     text = "\bf TEST",
     kind = "path",
] ;

path q ; q := for i within p :
     if picture i :
         pathpart i &&
     fi endfor cycle ;

draw q
     withpattern
         textext("\TEX")
         withpatternscale (1/20,1/20)
     ;
\stopMPpage

so the trick is to come up with a pattern that has the right size

Hans

Well this is fun.  Getting the right patterns could make some 
interesting with fonts.

Thanks for the tip Hans!
