Viewport Selection Outlines have Vanished

I updated my AMD graphics card drivers from 16.7.2 to 17.2.1 and my selection outlines in the viewport have vanished entirely. I tried changing my editor look and feel settings to no avail. This affects old and new projects. The only way I can bring the outlines back is by installing the outdated 16.7.2 drivers, I’m using an RX480.
