Disable emojis. Seriously, the animated emojis must be implemented with something like this

    while(true) {
        foreach(emoji) {
            emoji.refresh();
            if (emoji.since_last_frame() > 1/60) emoji.next_frame();
        }
    }
Slack can easily eat up one core with just a few of them on the screen. Never seen that.

IIRC, the last update on OSX specifically mentioned that they were requesting the emojis way too often, and that it's now just doing it once.
