I had issues with urxvt and ended up moving to Kitty (https://github.com/kovidgoyal/kitty). I'm not impressed with its' autoupdate feature, but it can be disabled. Apart from that a few visual bugs which are probably to do with nvidia the terminal is great. The best feature? Emojis render flawlessly.

I had a proof of concept, but hackernews doesn't support emojis :'(
