Issue

I’m using Fira Code font and the ligatures don’t work. I found this issue https://github.com/zeit/hyper/issues/914 and tried installing the hyper-font-ligatures add-on or adding this css

termCSS: `
  x-screen x-row {
    font-variant-ligatures: initial;
  }
`,

but none of these seem to work.

@nurtext Because technically this bug was resolved. The ligatures work without WebGL renderer. I think another issue should be created addressing this.

@orangecoloured I understand, but for me it’s still open because turning off the newly introduced renderer isn’t a valid fix. Ever tried tailing or cating some logs with the old renderer? It made Hyper almost useless for me. Now Hyper is back in the game (at least for me), but ligatures are a must have in 2019 IMHO.
