Font Problem

[ghost]

Hi,

This is how xterm is displayed with defaults.
I tried to change font-family & line height.
What is the problem?
I am using your startup example.

Details

• Browser and browser version: Chrome 67
• OS version: Ubuntu 18.04
• xterm.js version: 3.4.1

Steps to reproduce

Hello, your issue looks like related to #1170

Had the same issue on debian buster/sid / Firefox ESR 52.8.1 (64-bit), fixed it by changing the font family to Courier New

const xterm = new Terminal({ fontFamily: 'Courier New' });

Hi,
I added fontFamily:'Courier New' option to constructor.
But nothing changed.

I added this to the constructor, which fixes the issue for me on Ubuntu 18.04 and Chrome 67:

const xterm = new Terminal({ 
    fontSize: 14,
    fontFamily: 'Ubuntu Mono, courier-new, courier, monospace'
});
