KWGT Widget Not Stable

All of a sudden one of my KWGT widgets is unstable. The battery bar will move indiscriminately and then reset itself to be accurate. A fonticon with a touch action I just added to the widget keeps disappearing and reappearing and overall different pieces of text and the formatting will blink in and out and move on its own while I am just looking at the screen. Then the widget will be fine for several hours and go back to being unstable again. Any suggestions on what could be going on?
