Graphical Glitches Plaguing Some 2020 iMac Owners With Radeon Pro 5700 XT GPU

Apple has already addressed this by updating the product page
PS: Connecting an external Monitor to the Mac Pro 2013 resolves this issue, too. So the similarity is stunning.
So here's the question... is it apple that is giving us super poorly implemented drivers or is it amd?
Must be fake news! Read this:
About macOS GPU drivers
Mac hardware and GPU software drivers have always been deeply integrated into the system. This design fuels the visually rich and graphical macOS experience as well as many deeper platform compute and graphics features. These include accelerating the user interface, providing support for advanced display features, rendering 3D graphics for pro software and games, processing photos and videos, driving powerful GPU compute features, and accelerating machine learning tasks. This deep integration also enables optimal battery life while providing for greater system performance and stability.
Apple develops, integrates, and supports macOS GPU drivers to ensure there are consistent GPU capabilities across all Mac products, including rich APIs like Metal, Core Animation, Core Image, and Core ML. In order to deliver the best possible customer experience, GPU drivers need to be engineered, integrated, tested, and delivered with each version of macOS. Aftermarket GPU drivers delivered by third parties are not compatible with macOS.
The GPU drivers delivered with macOS are also designed to enable a high quality, high performance experience when using an eGPU, as described in the list of recommended eGPU chassis and graphics card configurations below. Because of this deep system integration, only graphics cards that use the same GPU architecture as those built into Mac products are supported in macOS.

It's Apple's fault for inhibiting competition for different video suppliers in their machines, leaving heir customers with only one choice of vendor.
Good question, apparently it’s Apple? Based on what they say on their site.
But surely AMD give them a tonne of base code to work from.
That's my take on this as well.
I have an older, Actually 2 from 2012..MM & MBP, and the MM has GPU glitches in Safari since years, I rarely use my 2012 MBP so I don't know if it occurs on that one too.

How will that help?
Sorry but it is not the same issue.That's interesting. It seems to be exact the problem I (and some others) experience with my Mac Pro 2013 (Dual D500 graphic cards) since Mojave. It became worse and better through the updates, but I never got really rid of it. Today with latest Catalina Updates I still see it randomly, but mainly when scrolling up or down. See this thread: https://forums.macrumors.com/threads/mac-pro-late-2013-gpu-driver-issues.1860297/
When installing Mac OS High Sierra there is no graphic glitch at all. So I am still convinced it's a driver issue here. May be this is getting more attention now and there will be a fix for all of us. Let's hope at least.
MP 6,1 2013 was freezing crashing restarting because of the GPU.
iMac 2020 has an issue with a line flashing randomly, a glitch, and a rendering problem at the top/upper corner of an app. No freezing at all, it is distracting and annoying and produces some worries for the future.
Every user hopes it is not hardware related. The common thing is Apple's silence...Of course AMD/Apple's GPU drivers need some attention and fixes.
I’m the user who created that thread. One other fix that isn’t mentioned in the article is attaching a secondary display. I have been running an external 1440p monitor for weeks and I haven’t seen the issue once.
I had been planning on running an external display so this isn’t a workaround for me, it has always been my intended use. It’s not a good solution for everyone but it works for me.
This is also not a problem in Windows running bootcamp so it’s almost certainly a software issue.

It's Apple's fault. At the end of the day Apple is solely responsible for the development and release of it's drivers. AMD provides assistance, but Apple controls the whole thing.
Ahhhhh finally! Thank you MR for posting this!!
I don’t disagree. Again PlayStation and Xbox runs AMD GPU’s just fine.
How is this not apple's fault? They decided on the hardware, wrote the software, and built the machine. They are responsible for what is delivered as a final product.
If they can't figure out how to make existing architectures work in a form factor thats been around for 10 years, goodluck on thier new endevors 😂
I love apple dont get me wrong, but they''re not perfect and they should be held accountable for thier mistakes.

I was going to say it’s almost comforting to see Apple users experience some of the AMD 5700 GPU/driver issues that so many in the Windows world experience (including myself before I gave up and switched to nvidia).
Thanks for increasing awareness of this MacRumors. - I'm having graphical corruptions in macOS Big Sur as well, so it's still not fixed in the latest beta of that.
Probably on their higher end Pro machines.
But I believe there was already confirmation that they will be designing desktop class GPU’s with their new Apple silicon. Just as they do for iOS A chips.
I have both visible errors on my iMac (Retina 5K, 27-inch, 2020) with 10-core and 5700 XT.
- Random white lines within the screen (YouTube videos within Safari is an easy way for me to reproduce)
- Rounding of windows have white corners and don't appear rounded, but squared off.
- This happens with or without an external display connected and whether or not I'm using a scaled resolution

makes sense for Mac Pro. not for iMac, especially when Apple cares about thinness. iMac Pro, maybe.
also this rumor suggests differently: https://www.macrumors.com/2020/08/31/apple-silicon-imac-custom-gpu-2021/
For me it is EXACT the same issue like with the new iMac. I had never any crashes with my Mac Pro and D500 cards. But I see this white line flickering on the right side of the screen. Earlier there were many lines flickering, but it got better like I said.Sorry but it is not the same issue.

I feel for all you having issues. Let me grab my ouija board and me and my 2009 iMac will send good thoughts.
