Are you sure the flickering in yours fit to description of sporadic quick blink of an eye long flashes usually on the lower 1/3 of the screen? Like in the link I posted on the previous page of this thread, or like one in the beginning of this thread?
I mean there are obviously many kind of flickers and surely some of them can be hardware based.
Especially if it is something that happens when you move the machine or the lid and I guess if it is overly common, like hourly or even more often I guess. In my unit it is like twice on month or so. I just saw once this week and I used the machine like 4 hours in a row after seeing it and it never happened again during that session.
You did not test Catalina yourself?
Like in the post I linked on the previous page there was one who confirmed getting rid of them after installing Catalina and it was like couple weeks ago or more use without issues with that one, and based on the description and videos of the problem that guy was suffering from exactly the same kind of flickering as what I see in mine.

i just turned off true tone and auto-brightness.
let's see if i see the issue at all. going to be paying close attention.
Thanks for the video. I have the same issue (only gray patterns) with my 3 months old MacBook Pro 13" 2019 Core i5 2.4 Ghz running macOS 10.14.6. I think I will send it to service.

2018 13" MBP i5 checking in. I also have this same flickering problem on occasion at the bottom of the screen. Hard for me to reproduce on command and it will occasionally go away then come back again as has been reported in this thread. I ran Apple Diagnostics to try and rule out a hardware issue. Everything came back normal.
Do you think it might have anything to do with Dark Mode?

I have the same problem with my 2019 MBP 8gb 128gb. My issue is also in the lower 3rd of the screen. I haven't been successful in capturing it yet. I have my GoPro set up to capture it though. I have not found a way to recreate the issue, it is just random. Following this thread to see if someone eventually reports a solution.
Well, was just replying to a post on here and the whole safari window freaked out like it does on the lower 3rd of the screen, and of course, I didn't get it recorded. This is becoming frustrating.
i disabled true tone/autobrightness and so far it has not occurred but its only been a few hours.
Thats it! But service could not change anything =)

you will have one more chance I promise you
Are you sure you wanna go that route? I suggest reading first few threads about this issue and peoples experiences with service and software fixes they have tried by themselves.
I had this happen yesterday on my less than week old 2019 1.4GHz 13". I moved to adjust the hinge and bam. Lower 3rd, horizontal interference.
Hasn't reoccured yet, but I will be looking for it. It might be software. From what I've seen, on Apple laptops display cable issues manifest as vertical distortion, not horizontal.

Today, when I was exporting some images on my 2018 MacBook Pro 13 inch (i5 2.3GHZ, 8GB DDR) using Capture One Pro (latest version), I noticed a pink flickering bar on my screen as well as strange characters (black, above the bar). This issue only appeared 2 seconds, disappeared and later on reappeared again for another 2-3 seconds.
This was enough time for me to capture an image, which I uploaded here: https://ibb.co/LpKCmZw (I cannot seem to find a way to display the image in my topic. Apologies for that).
From time to time, I have noticed a small flicker (e.g. in the bottom of the screen), when watching a video on HBO or Prime Video in Safari browser as well. This however seemed to be completely random, hence never thought much of it.
Something like the image under the link above, I have never seen before, hence its rather worrisome. :-(
P.s. please note, the dark red spots (e.g. above the C1 "exporting" window) are C1 exposure markers, hence are not an issue.

I read about this on forums and I have proceed the steps like rebooting in safe mode, resetting NVRAM, etc. I think it's a hardware issue and I would like to ask for a replacement unit instead of hacking a faulty one.
Good luck with that. As far as I know they do not replace MacBooks, they just replace parts in them. Only way is if you bought it from Apple that if you return in within two weeks, you can refund/rebuy or even just exchange it to another unit, or if you bought from reseller who has good return policy you can return it but other than that you are out of luck getting a new one.
I'm not sure if AppleCare give you possibility to get a new machine?? That might be a workaround to get another (is it new or refurbished?) one?
As you may have already read, some peoples have tried service centers and ended up "Frankenstein" machines with several parts exchanged but the original problem still there. Sure you may get new one if you return it many many times for the same fault but then again this flickering usually manifest itself so rarely you have small chance you are actually able to show it to them and even if they change parts it is again almost impossible to make sure it does not happen again as no service center have possibility to have one worker sitting in front of a one machine for two weeks in a row staring at the screen non stop...
As a side note since you mentioned seeing a full screen distortion pattern in your unit, the problem might not be the same as what I and many other have where screen just have distortion pattern flicker in lower 1/3 part of the screen...
I personally will wait to see if Catalina when released bring fix to this before even thinking about service possibility, and even then I want to hear few peoples actually getting machines repaired so that problem is not happening again.

I don't think so that Apple has the right to give back faulty "Frankenstein" units to customers in the EU. I'm not a lawyer, but to my best understanding, sellers have to replace their product it if they are unable to repair that.
As I mentioned earlier I had the partial screen distortion (maybe in the lower 1/3, I don't remember) with the same grey patterns, full screen issue is new.
Yeah, I'm in EU too and usually here it is like that you have to give seller possibility to fix the machine, they are not required to just give you a new one if it became faulty! Then usually you have to give them like three attempts to repair it, for example send it to service center for three times and wait for each time that it gets repaired and it does not have to be immediate repair but like couple week at the time (depending on the machine and about how important it is but couple weeks at least is normal). So after you have gone thru that for three times, you may try to ask for a new machine but you must convince them it is the same fault every time. It gets hard it they for some reason interpret the problem a bit different each time. I'm not saying it is impossible to get new one or even refund but it is hard. I've gone thru that with other brand devices few times and I have got even refund or the new machine sometimes but it is very time consuming and not easy but sometimes ended up with "Frankenstein" machine in the end (it has been repaired and works but it looks like abused cosmetically and so on).
So you cannot just go and say, hey my screen is flickering once every two weeks for 0,5 second at the time, please give me a new machine right away... It just does not work like that. This is what I'm trying to say.
So maybe your unit has different problem than what usually is with these. But again, you have to go thru that service procedure.
I think the problem is nearly similar, I don't want to repeat myself. The same grey checkers appeared here for a fraction of a second with random timing, non-full screen, just as seen on the videos, for many (30+) times. Maybe the full screen issue is different, but the original fault is also here if you want to differentiate.
I understand your point of view with services, let me see what happens. I will ask for a replace or refund when contacting the seller since this looks like a known issue with the type with examples on the Internet now. I think it's different case compared to a "normal" breakdown of a random device.
Me neither, but near identical does not mean it is the same problem. Could be or not.
Good luck with that. Please report here how it worked for you.
But again, good luck with trying to convince dealers about this based on the "internet rumors". Probably if you are the first one ever at the shop you might get passed but usually dealers have seen cases like that before about "internet rumors" and they just ignore all that. It just is not known issue until some company or officials admit it in public.
Again, I definitely share your opinion about that we should get a new machine whenever there is a situation like this but it just does not usually work that way in the real life. Believe me, I've gone thru that process before (never with Apple but I don't think it is any different than any other company)

I guess that may work, at least temporarily. I've heard one theory from someone who was debugging the problem that it has something to do with the way TT is handled thru T2 chip and somehow it may get corrupted frame in frame buffer and that the problem can be fixed by clearing NVRAM and PRAM. I think root cause for the problem is somewhere around that. Lets just hope it is fixable. From what I have heard it should not occur with Catalina, so looks like it is fixable.
It would be also interesting to hear if peoples who leave their machine usually in sleep mode suffers from this more than those who power off. I always power off mine after use and so far I've seen this flicker only rarely. I have TT on all the time but auto brightness is disabled. I also have NS engaged at certain time.

That video perfectly shows the artefact I get occasionally although the blue tinge is the main issue I get.
I noticed that in the UK you can return an item for refund or replacement if its faulty within 6 months and the provider has tried to repair it without luck. Unfortunately software repairs don't count, so I need to put the laptop back in to the store to get looked at. Which is a week's wait for an appointment and then a further wait to see if they'll replace the logic board. They didn't last time as they couldn't replicate the issue.
The blue tinge comes and goes as quick as the display artefacts, so getting a picture of it has been nigh on impossible. Really frustrating.

But you can show them the video posted on this site, right? Just put it on your phone as if it were done on your machine.
I haven't heard of this happening on the 15 which is strange. There are things that lead me to believe that it's a software issue, but, if it is, then why isn't it seen on other models? It might be due to more graphics horsepower on those other models of course.
