Install typeface-roboto in npm "import 'typeface-roboto'", when the font is loaded, the delay occurs when the font is applied at the initial loading. The point at which the font is applied is applied after the page is loaded and there is a flickering phenomenon

react 16 version create react app 2 environment is using material-ui 3 version

This occurs in the webpack dev server development environment
