Still here.
I have set up a new monitor for my laptop. AFAICT, the problem with the original display has to do with the connection between the graphics card and the actual display. The big clue was when I changed the angle of the screen and suddenly the image cleared up. Unfortunately, it didn't stay that way. Then I found out that the webcam that I bought ages ago and never used also had a faulty connection because I need an external webcam due to the laptop's built-in webcam now having a lousy LOS of me. Fortunately, it turns out there're ways to turn a smartphone camera into a webcam.
