Individual Apple message text looks staticky
I have received a message from my father that on my screen is not visible because it looks like a million ants marching around or in other words, staticky. You cannot read the message until you place your finger on the message and the "static" clears around your finger, but the rest of the message remains staticky. If you run your finger over the entire message the static clears so that you can read the message in it's entirety but soon afterwards the static comes back. Why is this happening? Is the sender doing something to the message prior to sending? How do you stop this from happening.
