Hi @JackRenz16,
I'm sorry to hear that. I would recommend that you make sure you don't have developer options enabled in your device. You can turn it off if you go to: Settings > Developer options > Off (If you can't find developer options under settings it is already off).
I'd also suggest that you try and reboot your device to safe mode to see if this may be caused by one of your downloaded apps as they will be temporarily disabled in this mode.
If they behavior persists you can try to do a software repair using Xperia Companion to rule out that this behavior of your screen is related to the software in your device.
Let me know how it goes!
