My wallpaper just disappears and comes back after sometime

As I mentioned my wallpaper just disappears out of no where and comes back after sometime time. This has been happening only after I installed g helper (I'm not sure if it's due to g helper tho)

If its taking too much time for my wallpaper to re appear again, i just open task manager, click on windows explorer and then restart windows explorer. Boom, everything comes back to normal.
