I'm using !XTerm*faceName: DejaVu Sans Mono
and my xterm -> mosh -> screen -> irssi crashes reproducibly when resizing the window in the irssi tab. At least it did so 10 times in a row before starting to reply here ;) Yeah, and now it happens again - resizing the window _sometimes_ works in a plain shell window, in the IRSSI window it reproducibly crashes. Another font file is being opened, though: 13967 17:30:55.114945 openat(AT_FDCWD, "/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf", O_RDONLY) = 5 No missing glyphs that I know of ... how would I see them? Still I don't see why it should crash because of that.
