@gaearon I'd recommend that you remove "window.zoomLevel": -1, and make the following font setup.

// Fonts Setup.
	"editor.fontFamily": "Operator Mono, Fira Code, Menlo, Monaco, 'Courier New', monospace",
	"terminal.integrated.fontFamily": "'Operator Mono', 'Inconsolata for Powerline', monospace",
	"editor.fontLigatures": true,
	"editor.fontSize": 17,
	"editor.lineHeight": 24.65,
	"editor.fontWeight": "400",
	"editor.letterSpacing": 0.5,
	"workbench.fontAliasing": "auto",

Obviously chose your own font there. Make sure line-height is 1.45 times the font size.
