I've been having this problem for a while. I never bothered posting it but its getting really annoying. My problem is whenever I download or uninstall an app and press the home button, my widgets replace each other on the home screens. This problem also happens when I reboot my phone. I am rooted and using stock. I tried factory reseting and same problem. I even restored stock and rooted again and still getting the same problems. Really frustrating. I have enclosed a couple of screens shots for you to get an idea.
