Hi everyone, can somebody explain to me what this is? it is only noticeable on dark grey/blue, but I am afraid it could get worse and I would also like to understand the cause. I noticed it suddenly yesterday. I do not know if it can be useful to say that I use the laptop every day for many hours, but I only use chrome. You can't see it well from the photo but the line runs vertically across the entire screen
