Scene View shows distortion, colored lines/static

Hello all. I could really use some help here, as I’m a complete noob.

When I load any project (new or existing) into Unity Editor, it shows me weird distortion/noise in Scene View. It looks like this:

Everything else seems to work. I’m using a brand-new MacBook Pro 16" and the latest version of Unity (2014.4.0f1).

Oddly, everything was working fine until last week, when I started seeing this distortion. Advice would be VERY appreciated.

@neutralica Did you manage to fix it up? I’m facing the same issue still.
