Strange vertical line across the MBP screen

[AMSOS]

I am seeing this weird line vertically across the screen of my MBP 13" (early 2015) laptop. The machine had been shipped with OS Yosemite and I have about 4 months ago upgraded it to OS Sierra. I haven't installed any new software recently.

This happens often when I quickly switch between tabs while browsing the internet. It stays for less than a second and then goes away. When I switch between once tab at a time I don't see the line (See attached screenshot).

I am not sure what this is, but I do know it wasn't there barely a week (or even less) ago.
Is this normal for older laptops? Does it have something to do with the logic board or display? And how worried should I be about this?

My MBP has given me 3.5 years of service and I am out of extended warranty now.
Thanks!

Mine is a 2015 15” refurbished retina, same problem. I had it since day 1. I’m pretty sure it’s
the screen. I plan on taking it in this weekend.

Is the line relative to the physical dimensions of the screen? Is it always 2.78 inches from the left? Or whatever? Or does the line appear 2.94 inches from the left when the browser window is moved?

Strange either way, but I'd suspect a hardware issue with the former for sure.

If it occurs only in Safari and is relative to browser window, then it's certainly a rendering bug in Safari itself.

Yes, it is in exactly the same location at the same distance from the left side of the screen.
No, I am not moving the Safari window at all. I have numerous tabs open and I see line make an appearance when I quickly cycle through the tabs using Ctrl+Tab.

Stupid of me to not check this before! I opened a lot of tabs in Firefox and cycled through them quickly and....... nothing!
It's happening so far only in Safari. Grrrr...
What do you suggest I do now?
Also, let me tell you that I've had 3 tabs open permanently in Safari. So, I leave them open when I press Cmd+Q to quit. I do this every time and these 3 tabs load up every time I open up Safari anew.
Thanks!

If only in safari happen it is an software issue
You have safari 12.0.1?

I had something like this happened to my 2015 13" MBP but it covered the whole screen. Eventually, it started to glitch my screen and I had to take it into the genius bar.

Ultimately, my screen was affected by "staingate" which is a staining issue for any retina display that you cannot wipe off. Since my screen showed signs of staingate, they replaced my screen for free which ultimately fixed the vertical lines. Without that stain, it would've costed ~$500 to replace the screen.

Yes, I do. I must have updated about a week or so ago. And I just realised that that is probably when I started seeing this line!

"About Safari" tells me - Version 12.0.1 (12606.2.104.1.2)

So much for the manufacturers chiding users for not updating to the latest softwares!

Nothing You can try reporting this bug to Apple though. I'm sure they will fix it eventually anyway.

Ha, ha. Thanks anyway. I feel relieved that this didn't out to be a hardware problem. The display of my MBP has already been replaced because of the well-known issue with the Retina coatings. And now that I am out of extended warranty I would have been in a tight spot if it turned out to be another display problem.

If it shows up on a screenshot, it's certainly not a display problem

Mine isn't dependant on browsers, but more when I'm switching through colours quickly.
