Ubuntu – Ubuntu 19.04 background kind of pixelized


I have a problem with my Ubuntu background. It seems to get some kind of pixelized. I searched the internet but couldn't find any solution. My background is the default background from Ubuntu 19.04.

The problem usually occurs after I put my notebook in hibernation mode. I recently installed bumblebee with nvidia drivers. Bumblebee is from the official repos and the drivers from the nvidia ppa.

I'm looking forward to your answers. Thank you!
