Strange glitch in messaging app

Opened the stock messaging app and this blank white box blinked on and off the screen. Restarted the app and it went away. Strange....

Looks somewhat similar to the box that pops up when you tap on a contact's photo, except it's slightly different. And blank. Just one of those one-time quirks, I'd guess.
