You can choose the font with `twin --hs=X11,font=X11FONTNAME` or `twin --hw=xft,font=TRUETYPEFONTNAME`

I will have a look too, the terminal should not crash or stop being responsive

Thank you. Weird that this isn't in the man page or --help message. Another font didn't fix anything anyway.

I tried compiling https://github.com/panzi/ansi-img and running it inside the truecolor branch of twin, i.e. https://github.com/cosmos72/twin/tree/truecolor and it correctly displayed an example JPG I tried - no artefacts, and terminal remained responsive.

As I wrote above, I am debugging it and fixing some known issues, thus truecolor support is not yet in the default branch
