Display Related Issue.

I am using pop os since last year on Asus Zenfone 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 beca

use of it. Any help fixing the issue is appreciated.
