Ended up restarting the machine. Looking at the Beta APFS volume I created, nothing got installed. It's just the standard installer files and nothing else. Or so it seems. Let me know what your experience ends up being.
Got a tip for us?

iMac 2020, 5700XT - graphical glitch?

Yep, same. I rebooted in verbose mode just to see if there was a specific error. It hangs very early on during boot up, see picture:
I thought the failed installation had something to do with the extra security that comes with the T2 chip, but that doesn't seem to be the culprit either. Assuming it is not compatible. We did sort of laugh at what seemed like a typo in their release notes... mixing up beta 6 and beta 7 verbiage. Let's see what @tjramage says.
I don’t blame you. Here you guys are working for Apple, yet paying them. How’s that for irony?! It’s become glaringly obvious to me that ‘we’ are now Apple’s QC and beta team. The problem is we work for free. ?
(Had some issues with this thread not updating.)
I guess we've then collectively figured out that Big Sur does not want to install on these machines. Yet. I was hoping that by doing this test install we could've determined if Big Sur will be "the fix" or not. Of course driver updates and such could also be very last minute before Big Sur officially comes out... so, not something we would know 100% today. Also, I would’ve tested what software (audio plugins specifically) that I currently rely on would continue to work in Big Sur. To see if it’s an option for myself and others to immediately switch to Big Sur when it’s officially out. I guess we’ll continue to wait.

How about using your iPad or iPhone as a second display using Duet Display or Sidecar?
Thank you for putting in the work. Team Apple should send you a check. They can just sit there and watch this thread receiving clear direction on what’s working and what’s not...

Don’t know the answer to that either, but excellent question!
I haven't seen a single graphical issue since connecting my external display (1440p via a USB-C to Displayport cable). That said, I didn't have/notice the window corner issue so I can't speak to that one. But the white line hasn't been exhibited at all.
Totally bizarre why having another display connected would remedy the issue. Whelp I just ordered an LG QHD display off Amazon. Awfully sneaky how Apple has gotten me to play their ‘workaround’ game and spend more money huh?
I’m not referring to testing BS. I’m referring to all the work we are doing here to try and figure out what the issue is with the 5700 XT machines.
That 'signing up' makes me think you're using the public beta rather than the developer beta, which I believe is still at beta 5 (someone correct me if I'm wrong!).
This has been corrected; the release notes now say beta 6.
Thank you for this post! This is bizarre but my profile was set to the public beta program. I had to re-install the profile from developer.apple.com so it says Developer Seed Program again. I must've inadvertently tried installing the public beta 5. And of course that's what @tjramage must've done, right? Failing to pay attention to things today! Gah! Re-downloading now. This should be the real deal.
I don’t think this is affecting sales yet because people are none the wiser. It will take awhile before these issues totally catch fire. It’s super hard to notice if you even blink. I’d say we are only simmering right now. Also, I don’t believe there is any such thing as ‘special priority’ with Apple. More than likely Apple won’t even touch this until the BS GM, which is quite troubling. ?
Apple has a profile tool that sets you either as a public beta tester or a developer. I'm an Apple developer but had my profile set to public beta somehow. No idea how. Never seen that happen before. So, we were both trying to install beta 5. Which does not work on these machines. I didn't even think about that when you said you had signed up to download it. And I didn't spot the difference in System Preferences > Software Update.
Ahh I see... There's a yearly fee to get access to the developer stuff, right?
Looks like you're on your own from here!
