I am using pop os since last year on Asus Vivobook AMD Ryzen 3500U. I had some issues during installation after that it worked fine without any major issue till few weeks back when i started face issues like system freezing while doing basic task. When my system froze i thought close the lid and then opening will help instead my system turn pixelated. Image for reference. I have lost a lot of my work in last few weeks because of it. Any help fixing the issue is appreciated.
This looks like a hardware problem. Can you attach an external monitor and get a good image? If so it is a problem with your display if not then it may be the graphics processor. Also you may want to check for video driver issues.
