8 years ago Tagging @jonathanolson because he might be interested in this problem.
Following the directions above, I was not able to see this problem on iPad3 running iOS 9.2 (13C75)
@elisemorgan can you try restarting Safari (double tap the home button, then swipe it away), and restart the iPad2 and see if the problem persists? If the problem persists after restarting safari and restarting the ipad, please launch with ?screens=3 and see if the problem is present (this could point to a memory/context problem if the problem disappears with ?screens=3)
