I have noticed that [Input] has some display issues.

• This is not a v0.x issue.
• I have searched the issues of this repository and believe that this is not a duplicate.

Using https://material-ui.com/demos/text-fields/ :

• There is visible line through outlined label [Input] on hiDPI screen in Chrome 69
• There is sometimes visible scrollbar on multiline [Input] on hiDPI screen in Chrome 69
• Textarea is not growing when you insert just empty lines in Edge 42
