Touch screen issue

I just started to notice that four of my apps from the upper area from the second screen intermittently become unresponsive. Is this a known issue? Is there a way to fix this? Thank you!!!

This is weird but I change my wallpaper to live earth and working much better. Just FYI for anyone that might have the same issue. I was using the Aurora from Google default wallpaper.
