Solving a Washed-Out Display Problem – TidBITS

Some months ago, I noticed that something was slightly wrong when I was using Google Chrome. I’d type something in the address bar and get the auto-complete suggestions appearing below, but when I arrowed down to select one of the items in the list, I couldn’t tell which was selected. It was as though I’d lost the gray highlight color. It happened on both my iMac’s internal display and the external Thunderbolt Display, and none of my usual troubleshooting techniques helped explain what was happening. I eventually shrugged and chalked it up to gremlins.

Every now and then, I’m confronted with an inexplicable problem on a computer or iOS device. Sometimes, the solution is quite simple, but hard to find.
