I fear the day big sure will be released and nothing has changed. This will fade away the small amount of hope I still have to one time by a perfect machine.
As I type this 78 people with the 5700XT have the issue on this thread (it's been 78 for a couple of days). Worldwide I guess they'll be thousands with the 5700XT who don't have the issue, have never felt the need to Google it or document any lack of issue by voting here. I think we're in an unlucky minority.
There was a front page article on this issue yesterday or the day before. It specifically mentioned this thread, which was at the time 57 pages long.Consider that the vast majority of Mac users may not be savvy to search for Mac websites. Many Mac users are non-tech people.
Also, this website, if it had a heart for its users, would place this issue on their front page, in order to find out if there is a wider population of people struggling alone, and not aware there are others. (... the hand that feeds ...).
Note also, that the only way to find this forum article is to search for the word "glitch". Many people out there might use different words to search, and hence not find this forum article.
If there were only a handful of users with this White Horizontal Line issue, then how is it that countless people have returned their iMacs and the replacement iMacs have the same exact issue. That's like winning the White Lighting Lottery. Common sense tells us that it's "limited problem" which is only affecting some users, isn't so LIMITED.
If you have the issue, you should vote that you see it. we already established that an external monitor will resolve the issue. But that wouldn't warrant a no vote, because it clearly has happened to you.I have the issue but haven’t voted in the poll. Want to try using an external monitor to see if it goes away before casting a vote.
Several people in this forum have returned their iMacs and received new ones with the same issues. If 25,000 iMacs with 5700XT were sold and this only affected a limited # of users, then the chance of getting two duds is so remote. In fact, I was one of the people who ordered 2 iMacs a few weeks apart from each other (both iMacs had the issue). What are the odds? Is there a mathematician in the group?I'm surmising... if only 78 (it's still 78) have found their way to this forum but thousands of units have been sold... then ye, unlucky 78. I'm one of 'em.
29 people who presumably already frequented this forum saw this thread, have the same 2020 iMac configuration and voted as not seeing the issue at all; so (if everyone is being observant and straight about their experience) I'd surmise there are plenty of other people out there who are also happy with their 5700XT purchase whom we have no knowledge of.
I'm not an Apple shareholder, I'm just looking at the available evidence, my own experience in this matter and drawing my own conclusion.
This has been addressed multiple times. Please read the thread or search.Someone tried to set up a dual boot system and booted up in Mojave ( procedure can be found on the net) and see what the outcome is ? If it stays away it is for sure a Catalina thing if it persists than it’s either a driver problem or a hw failure.
Apple always uses that storyline. Steve Jobs got on stage to claim that fewer than 4% of customers were reporting a reception problem with their iPhones 4, but it was clearly enough of an issue for Consumer Reports to blow it up and thousands of users online complained about it. 4%? I think not. But that's how Apple becomes a trillion dollar company. By lying, covering up, and writing its own narrative.If there were only a handful of users with this White Horizontal Line issue, then how is it that countless people have returned their iMacs and the replacement iMacs have the same exact issue.

Not those who are getting the 5700XT configuration. Those are otherwise iMac Pro customers who want a newer, more powerful machine. Pros know how to go online and write a complaint.Consider that the vast majority of Mac users may not be savvy to search for Mac websites. Many Mac users are non-tech people.
You have the issue, vote!I have the issue but haven’t voted in the poll. Want to try using an external monitor to see if it goes away before casting a vote.
It doesn't occur in Bootcamp. That points to a driver issue. I also wouldn't rule out some strange interaction with the T2 chip, which is new this year.My fear is, my original 8 core 5700xt had the issue and so does my replacement. People have it on Catalina and Big Sur beta... doesn’t sound like a software issue as much anymore. I suppose it could be a driver issue but it certainly could be hardware related as well. It’s not worth the risk of keeping it only to have the machine die out of warranty.
Interesting. The thing that jumped out at me from your configuration was the i7 CPU. Most of the reports here have been from people with the i9. Hm.
The graphical glitches I've seen, as we far as I understand them, are an irritation not a show stopper. I'm still of the opinion it'll be fixed with an OS or firmware update, but I didn't want to sit on my hands waiting with a expensive new machine that irritates me.
I will be buying another one at some point.
In the meantime.... back to the trusty 2012 cheese grater, High Sierra and a PC Nvidia GPU. Happy days.

I had a kernel panic recently that was caused by BridgeOS, which I believe is the T2 chip. Something is going on.Great observation. You might be onto something. I'll be testing mine when it gets here. On its own, with a 5K UltraFine attached to it and under boot camp in both configurations. Will report back.

And it's total BS because that shouldn't be happening. I haven't had a kernel panic since 2012, until now. What is this BridgeOS nonsense? What the hell has happened to Apple?BridgeOS kernel panics have been happening since the T2 chip was first introduced.

If you purchased a $100,000 automobile that had a misfire and it was not going to destroy the engine but was just an inconvenience, you would wonder why the $25,000 Kia ran just fine.
This is my first, can you tell? lolYou are right, this should not be happening. In my view kernel panics are a much more serious issue than a few GPU glitches.
How many Macs with T2 chips do you own btw?
You are so kind and patient in how you word this.
My Mac just got to Kentucky from Ireland.
I am sitting here livid this might be something I have to look forward to in a day or so, and although you say it is an irritation, I need to strongly disagree.

That is what I do not understand. The tolerance that Apple gets from the base regarding things that frankly should have been noticed in testing before general release and fixed.
Perhaps mine is fine. I do plan on running this with two monitors, but this is my first Mac in over a decade after my last fiasco with a display issue and I am so far in panic mode that the biggest nicest tech purchase I ever committed to that cost me around $4000 (!) will have a fault right out of the box.
When again, I could have spent about HALF on a PC that i am 99% sure would not have had the same problem with the same spec sheet.
Yup. I haven't seen them at all today, been on the computer for the last 6 hours working. But they always seem to show up at some point.I just saw the white lines for the first time after 8 days of use. It seemed to flash in a sequence horizontally on the right hand side of the screen.
Because dropping over $3,500 on something isn't enough? I spent more on this iMac than I ever have before on any previous Mac. Apple's prices are going up while quality is going down. That's not a winning combination.consider dropping some cash on AppleCare sometime soon to give yourself piece of mind... irrespective of ticket price, things can go wrong... and if they do in this instance AppleCare is a small price to pay to cover parts and labour up to three years down the line.
