Have noticed this problem the last two evenings that I was using my new iPad in Safari. While browsing the iMore site the iPad start to zoom and unzoom rapidly on its own, justa couple of times at first, then more frequently. While the zooming was happening I was unable to pinch and zoom myself. Noticed the pulsing continues if moving back and forth from Landscape to Portrate views. Closed the Safri and the Apps pages where pulsating as well. Ended up turning the power button off and then starting again. Thought this was a one off yesterday until it happened again this evening about 20 mins ago. Has anyone else experienced something similar with their new iPad? Mine is a 32G WiFi model.
