Images are getting mixed in the screen

I have a surface pro 4 and lately i have noticed that, when it starts, the screen is not working good, it mixes the images from previous oppened windows so it makes working on it impossible for almost 5 minutes and then it gets back to normal. I dont know if it is a hardware problem or software and I am worriend that if I keep using it the damage will become worst.

Hello and welcome first.
With internet connection, try uninstall graphics driver on device manager, marking the check that remove driver files and searching new hardware, so windows search drivers on windows update.
