HTC One Keyboard Issue?

[K2Kgun]

In every keyboard driven application, when I attempt to correct a mistake using the backspace key, I encounter a random problem: when I hit one or more backspaces, the keyboard suddenly magnifies, eliminating about 20% of the view and a yellow box outlining the entire screen appears. The box bounces around as I hit other keys and I cannot see the entire window into which my edits are being entered. The only way to make it go away is to flip the phone 90 degrees (landscape to portrait, or if working in portrait, portrait to landscape) and back to resume the 100% view and eliminate the spurious yellow outline. WTH is this???

I have had the same thing happen. When you hit the backspace key you are hitting it to too fast on the repeat. What is happening is you are invoking the "magnify by tapping 3 times quick" setting. You can see it in settings/accessibility/magnification gestures. Now it says it doesnt work with the keyboard but...
