Ok, I tried again, and now everything works much better!

This is what worked for me:

- tvncserver:

VNCSERVERS="1:joakim"
VNCSERVERARGS[1]="-virtualtablet -geometry 1920x1080 -nohttpd -localhost"

- fedora 30 in both ends

- turbovnc, external ssh due to funky ssh setup

- gnome desktop

- inkscape, gimp and krita where all tested, and works this time.

- desktop resizing works

I'm quite sure I tested this exact same configuration before sending my
mail last time, but now the results are different, for whatever reason.

Anyway, thanks again!
