So today I noticed some white zones on my screen, they are located near each other on the bottom of left side. I'm pretty sure it is not a stuck/dead pixels, especially since they don't look like a square, they are just random figures. I will attach picture to make it clear.http:// The most weird thing about this is that they disappear on black background, for example if I'm watching a video and screen is black I can't really spot them. I tried fixing it with one of those videos with flashing lights, but it didn't help. Any solutions/ ideas what is that? Thanks in advice.
