Have you been playing with Developer Options? Settings -> Developer Options -> Show taps.
If that's not it, must be an HTC thing. Look in Settings -> Accessibility.
^^^this. All the way at the bottom of developer options. "Show Touches"
From me to you by the Power Cosmic
The developer option for Show Touches is NOT ticked.
Thanks
Adrian
Turn Glove mode on so that the touch screen responds more accurately when you're wearing gloves.
From the Home screen, tap > Settings > Display & gestures or Display, gestures & buttons.
Select the Glove mode option.
When Glove mode is turned on, you'll be able to see where you've tapped the touch screen.
Could it be HTC's "Glove Mode"?

It was indeed glove mode, thanks very much, that's miles better now! And thanks to the poster who replied to all those who didn't read my original message properly saying it definitely wasn't show touches!
