Windows 10 doesn't show selections in File Explorer

I posted a less-invasive solution to this here https://superuser.com/a/1162807

The trick is to toggle on and off High Contrast Mode. You can do this quickly with the global shortcut:

Shift+Left Alt+Print Screen

Turn on high contrast mode, then press the shortcut again to turn off high contrast mode.

As an intermediate answer:

Restarting Windows File Explorer from the task manager may solve this temporarily.
Performing a full reboot (bypass fast-start)

Seem to temporarily solve the issue. And it hasn't returned since.
