MacBook Pro horizontal and vertical lines

2020 here!

I have a Macbook Pro 2017(13inch, four thunderbolt,3 ports) which is currently running MacOS Catalina v10.15.4 and is having the same problem as what is posted in this thread. I just noticed that there's a thick black line covering the dock area. Shutting it down doesn't work. Updates are not working as well. But after a few hours of resting, it's back to normal. But then, the issue will show again after a couple of hours using it. No physical damage was done. I was just watching a series and then it showed up! Uughhh!!!! It was never sat on or anything like that.? It started small, and just now as we speak, it's thicker and I can see lines now. Unlike before it was a thick bar or line. I also noticed way back, before this issue, that my screen has uneven color-tone on it's four corners!!!uughhh!

2021 is here...

My mid-2014 MBP is still a workhorse. I travelled a lot with it, and taking care of it as it was new always, you can hardly even notice any minor scratches. No drop, no humid air, nothing extreme has hit it.

Two weeks ago I upgraded to OSC 11.6; another weird coincidence that on the same day my screen started to flicker, and soon when the machine was heated enough, it had many tiny horizontal lines that you could observe only when you were leaning very close to the screen. I planned to sell it by the way before the M1X comes.... : (((

Then today, without any bend, drop, crack, a sudden LCD crack line appeared in the bottom left corner after the usual flickering after startup. All the minor horizontal lines have gone, because now I have this one coherent horizontal and vertical line on the bottom and on the left hand side. Covering most of the dock items, as well as mirroring down the upper part (header) of the OSX screen.

I have an assumption.
1. No matter how you take care of them, these LCD screens are freaking "old" techs, though beautiful, but because they are vulnerable and the bezel+cover is thin and doesn't protective (sacrificing it on the altar of design and mode) they will broke. Just a matter of time.
2. I think that it may or may not receive to much juice at certain GPU related updates which messes up their electronics. Not all LCDs, but there are definitely a lot of "Monday-morning" ones that are not so solid. Quite enough to fill a forum, but not enough to prove anything.

All you can do is that you bear in mind, when you buy an Apple Macbook for 2400 USD next time: according to the avg. best scenario, you buy a machine not for lifetime or 1-2 decades, but for seven-eight years (depends on your lifestyle, care, usage of course). I.e. I bought this laptop for 7 years for an instalment of 350 USD per year, approximately 30 USD per month. With continuous software update and it served me well.

That's not so bad.

As I wrote, I planned to sell it. But probably now it's better to keep it and wait until LCD screen price will mitigate to a normal level. 600 USD is a robbery for the same possibly faulty screen here in Europe. If it was 200-300, I would think about it.

Its probably a micro fracture. It happened to my MacBook Pro 16, did you use a webcam cover or did a piece of dust get stuck under the screen when you closed it.
