Unlocking Phone with Messages Open

[fins831]

Not every time, but I'd say sometimes (1/10) when I unlock the phone with the Message app open, the screen tears, it's like what I saw when my graphics card would overheat 10 years ago, just static pixelated dots, then the screen refreshes and all is well.

I've noticed this since 7.0, and it is still doing it in 7.1

Am I the only one?

I've seen an artifact like that from time to time, too. I never pinpointed it to one specific app.

I get it occasionally when I open the camera app.
