dude did you read all post of this theme?) They changed my logic board (2 month after bought) and NOTHING is happened

I'm sure you see what makes above and this issue in hand different? It is much different situation with product support for the tank engaging the enemy or warehouse full of spoiling food vs individual end user clients for the mass produced device with display that is flickering 0.5 seconds at the time every two weeks.
I mean sure I'm very annoyed by this problems and I want Apple to solve it, but until they admit problem at their product design or where ever they can debug this problem in detail, it is not going to go much forward. Local service centers do not deal with problem in that detail. They have time tables they have to follow and they are just basically swapping few parts, there are not many parts in these machines.
It is true this kind of a problem is a pain to diagnose and knowing how tight timing they are working at these local service centers they simply have no time to sit in front of one machine for days or weeks and stare at the screen non stop. I don't think they can much do that for one hour even. I'm not saying they should not but I'm sure they just can't due to requirements they are given how long they can spend with one machine diagnostic. They maybe run some programs or such and they simply cannot detect problems like this very likely. So in the end situation can and likely will be that even your machine has been sitting there for a week it gets actual attention in the end for very short time when they finally open the box.

What makes you think it has anything to do with this? I have it installed but I doubt it makes any difference. I don't even keep it running all the time, I just start it when I need it.
I was having the artifact issue and did the NVRAM reset and I deleted coconut battery and have not had the issue in 4 days. I was having it every day, multiple times. Now zero.
What made you think coconut battery was contributing to this? I use it on all my macs regularly, never heard of it causing any issues.
[doublepost=1568652781][/doublepost]
It's a program that tells you some details about your battery, health of battery, charge cycles, mfr date, etc. It's a pretty slick little program and is way more detailed than you'll find in just your system info about the battery.
So is your machine also flickering many times every minute? Did you read carefully about problem description? I understood this tread was about the flickering lasting like 0.5 seconds that occurs like every few days to couple of weeks. Obviously that person has different problem with his machine if it does it many times per one minute!!
Because my issue went away afterwards and other people have done all the resets and that didn't help. It's easy to uninstall and re-install if your issues still persist.
I don't think Coconut has anything to do with this but obviously NVRAM clear may fix it temporarily, like I mentioned earlier.

This is exactly what I think is causing confusion, since there are flickering caused by several different faults. Obviously those that occur very often or nearly constant are from mainboard (logic board as Apple obviously is calling it), or the display flex cable, or the display itself.dude did you read all post of this theme?) They changed my logic board (2 month after bought) and NOTHING is happened
Then there is this flickering that occurs very rarely (like days to weeks apart) and does not last for much longer than 0.5 seconds at the time. I guess those, like you who have gotten parts replaced in vain at the service center are because service tech thought this was also the same issue as those others but this obviously is not since no part exchanging or even exchanging the machine to new one does not help...

You did not try Catalina? Since like it has been mentioned many times in this thread that has confirmed working by someone in cases where 0.5 seconds lasting flickering is occuring very rarely. But again, obviously your machine has different issues since you are practically seeing constant flickering (you mentioned seeing it many times per minute).
Are we talking about in case where issue was 0.5 seconds flickering happening once every couple of weeks, or one of the other similar issues?? I posted links about that a while back in this thread.
Just in case, I was referring to this thread: https://www.reddit.com/r/macbookpro...13_macbook_pro_screen_flickering_main_thread/
Seems like those who had that very rarely occuring blink of an eye lasting flickering got it fixed by installing Catalina. Then again there are those who are obviously suffering from flickering (usually happening very often) caused by other reasons (likely broken hw). Also common seems to be that those who are suffering from very rarely happening flickering has not gotten any help by exchanging to a new machine or have parts replaced in their machines. I see a pattern here…
Anyway, I will sit tight and wait for Catalina release as mine is flickering so rarely that it does not really even bother me.
Well apparently my MBP is now pending return.
Although the adviser couldn't say 100% it looks like both the logic board and the topcase have been swapped out. (In other words barring external components completely changing the guts of the machine.
Always impressed with turnaround for the Japanese mail service - it's never been longer than 48 hours in the service centre and this time they've turned it around in a day.
Probably helps that I picked one of the "standard" configs so I assume they keep reasonable stock of the logic boards - if you have a custom build probably have to wait for it to be built and shipped from China.

Thanks for information but I think it would be better if you would create another thread or response one that is regarding nearly constant flickering prolems. Since this thread is about rarely occurring very short time lasting flickering (like in mine 0.5 seconds about once every two weeks, some peoples see is more often but still not many times within one minute like you reported yours doing). This is because some peoples may read only few last posts of this thread and get wrong impression that this very rare and sporadic flickering is so easy to fix by changing hardware as in your case. There has been also many peoples reporting going thru several service center trips with almost all parts eventually replaced or have gotten their machine replaced with new one many times but they are still suffering from this issue! So to avoid mixing up the two different problems.
ah ok.
anyways, i'm heading into the apple store today or tomorrow to speak to the manager. i'll fight tooth and nail if this isn't a software issue. i didn't pay 1500 dollars to swap parts within a month or so of buying the thing.
Good luck my friend =) But they will not change your unit. Only repair. It's a company politics. They can change iPhone or apple watch. Not MacBook. Sad, but true (c)
I don't think you will get a new machine if your 14 days return period has ended. Also what you think you will accomplish by requiring a new unit? I've seen many peoples exchanging their machines (some even several times) to new one due to this problem only to see that new unit does the same thing. I don't remember seeing anyone confirm that new unit fixed this particular problem (you must understand that there are also flickering caused by different reasons that can be hw related too but I think what this thread is about is not that (or I hope)), so your chances are probably quite slim at the moment. I think for a time being it is better just to sit tight and wait until they announce some fix for this problem. I don't think any store manager can do nothing at this moment until problem is acknowledged and fixed by Apple.

So I have now had my 4th repair. They replaced the logic board, touch ID and top case. Same graphics problem. Going back into the Apple Store on Monday. I presume I get my replacement laptop now it'll be the 3rd time this issue has happened.
I guess it must look cosmetically kind of a "Frankenstein" after 4 repairs?
Anyway, I would demand for a new machine in similar situation, just for so many repairs, but do not except the new machine solve the problem. It is likely nothing hw related anyway.
By the way, which parts they have replaced so far? I guess there is nothing than bottom plate and screws from the original unit by now.

i spoke to the manager and he told me to wait. since i complained about the issue during the 14 day window, i will be entitled to a new unit if the problem truly is hardware related.
as so many people in here have switched out units, parts, and still have a problem i agree with you.... this could be a software problem. I'm going to wait a bit longer until i decide what to do.
i will say this though... ever since i did an update on the machine , turned on and off true tone/autobrightness the issue seems to happen way less frequently.
Because a replacement laptop will be 2019 model and mine is a 2018, free upgrade lol
I also have this artifact problem on my 2018 MBP 13". I wish I'd found this post before taking it into the Apple store. My MAC was at the repair center for 2 weeks and they could not reproduce the problem neither did they find any hardware problem. I tried to narrow down the issue by connecting my MAC to an external monitor: weirdly, the issue never happens when I'm connected to an external monitor. I enabled screen recording with QuickTime; oddly, that also doesn't capture the problem when it occurs.
Very hard to say what the problem is. After reading this thread, I have gone ahead to disable True Tone and Auto adjust brightness. No idea if that will fix my problem -- I guess time will tell. Has anyone actually tried to get an Apple store manager escalate this to Apple OS team or engineering team considering the widespread nature to this problem?
