So this started back when I switched to Mint. I was installing it and the screen was bugging and tearing a little but nothing huge. Then after the install it started blinking. It was blinking the whole time I was using mint (2 months-ish), UNTIL I switched to kde plasma. For some reason it stopped blinking. I switched to endeavourOS shortly after and since it has kde plasma i thought that the blinking would stop. It didnt.
