Closest upstream issue I found was https://github.com/xtermjs/xterm.js/issues/3380 . But @nebulon tells me the latest 7.3 release moves xterm.js to some OpenGL based rendering, so probably this bug solves itself.

@girish thanks! That's indeed the fix..

@nebulon Yeah, I think so. Your forum is kinda a handy counselling outlet for comparing notes on these things, before going out into the wild of app support channels 🙂

@nebulon great, thanks!
