The Mac Pro 2013's also had graphic glitches that went away after a second monitor connection.. Began with Catalina.

I’m considering a 2020 iMac and was thinking of getting this card upgrade... I might wait a few more days at least and see how this goes! Sounds like a software thing to me from what everyone has said. Ironically (for the ‘simple all in one’) this is already by far the most head-scratching Mac purchasing decision I’ve ever had to think about(!) between pricing, specs, the upcoming transition to AS and my own needs, I’ve gone through a silly number of configurations on the store page and every time I think I’ve settled on it something makes me pause for a re-think again! This issue being the latest example.
I wish you all luck in having it solved ASAP, regardless.

Same. I ordered the 5700XT and then canceled it. I am going to wait as well. I will consider ordering the regular 5700 with 8GB if it seems like the XT issue is hardware related.
Did some testing in Xcode. By no means exhaustive.
But it looks like the only kind of window that does not exhibit the sharp corner issue is a window with a transparent title bar (see attached). I have never seen this widely used and most apps have an opaque title bar. As soon as I switch back to the opaque title bar, the corner issue returns. Whether the window has a toolbar (the area beneath the title bar or next to the close, minimize, maximize buttons) makes no difference. Whether the window has an actual title (the title text) makes no difference.
A typical real app window can obviously be super complex compared to what I tested and that combination of components can introduce issues on its own.
While doing this, I also saw one white line that extended from the edge of my test window to the edge of the Xcode window. With the white line appearing when the corners were rendering correctly, I wonder if there is an overall window drawing bug and it either manifests as square corners or as white lines but not as both at the same time.

you have 2nd monitor? i had this happen once booting into a LOL Game. i fixed it by turning the 2nd monitor off and when i turned it back on was fine
And, actually, when hiding mailboxes, the constant flicker goes away only if your inbox (or Sent, Flagged, or Drafts -- whatever you view instead of all mailboxes) is empty. If you have mailboxes hidden but you're viewing an email, the constant flicker when moving the window is there. So, here, it seems to be some kind of a combination of content being displayed inside the window versus not.
No, I don’t have a second monitor. It seemed to have been just a one off occurrence anyway.
Can someone create a poll to see how many folks are seeing this on their 5700XT?
Maybe the window corner issue is happening to all the 5000 series GPU but not everyone is noticing it but the white streaks are only specific to 5700XT?

I question whether it'll work; I was unable to capture the squared-off corners in screenshots and I suspect that the white flashes might be similar. I ended up sending Apple a photo of the screen because I couldn't figure out any other way to capture the issue (I was reporting the corner issue specifically, since it's easier to replicate and is likely the same root issue).
I included a link to this thread.
Doesn't make me feel warm and fuzzy inside knowing that this bug/issue has been around for a while (that post was from November 2019). I was kinda hoping it was new and Apple would address it. But why would Apple use this graphics card if they know it has issues?It's not exclusive to the 5700xt but also 5300/5500m MBP 16" . My guess is a driver problem with the 5xxx series that will be fixed soon hopefully since its affecting so many configs.

White line flash/flicker on external display - MacBook Pro 16" 2019
The last week I’ve experienced a weird bug / glitch that I’m unsure of what is causing it. For my 16” MacBook Pro I got a BENQ PD2700Q monitor connected through a HDMI -> Apple USB-C Adapter -> MBP. The flicker I experience appears EXTREMELY quick and with no apparent pattern. I always notice...www.ifixit.com
For now it seems like on the MacBook Pro 16" it occurs when an external display is connected (D-GPU activated) and on the iMacs its constantly.
When you do the screen shots, you have to do Shift-Command-3. If you in any way interact with the screen (such as attempting it with Shift-Control-Command-4) it may not work. I captured the on/off flickering earlier on in this thread using Quicktime screen recording, too. Still attempting to capture the white lines in a screen recording. But they are definitely more hit and miss. I was also able to capture the sharp corners when remoting from my old iMac into the new iMac. So, the corners seem like a definite software issue (and thus capturable) but the white lines are not yet confirmed to be so.
Nope. Installed and played a few hours in windows today, no issues. 99% it’s the drivers under macOS.
I"m going to change my resolution from the default to 2048x1152 and see if that helps at all.
I'll keep you posted.

Because the iMacs only have D-GPU and the integrated GPU on the MacBooks is using different non-AMD drivers.
Inclined to say that the white lines can not be captured in a Quicktime screen recording. Unlike the sharp corners. Had two instances of lines while recording. No lines were captured. And this could be simply because the screen recordings have a frame rate of 55.05 (yes, a weird rate) and if these lines happen within a single frame at 60 fps, you’d have to be really lucky to capture the lines this way. Or, they were not captured simply because it is a hardware issue or something else that happens after the Quicktime capture takes place.
The sharp corners may be a completely different problem, possibly a window manager issue. The lack of white lines when running Windows in Bootcamp does suggest that this is also a software issue but it might be a driver level problem. Normally you would expect a hardware issue to manifest in any OS and to not respect window borders.
The corners showed correctly on screen too? Can you test with other apps? This suggests a redraw bug in the window manager. Odd that it would happen with just the 5700XT though.
Well, like all things about this issue, it seems to be inconsistent. I just had the corner issue occur in a Finder window and was able to take a screenshot (Cmd-Shift-3) without the window fixing itself. The resulting screenshot showed the rounded corner though.
Interesting. Shift-Command-3 captures it every time for me. At least if it's the Mail window. But I've also seen other windows refresh to normal as I'm capturing them. I haven't yet experienced what you're describing: where it did not fix itself (it remained sharp) on screen while the screen shot shows it rounded. For me, if it stays sharp throughout the screen shot process, it shows up sharp in the resulting screen shot.
The two "versions" I seem to get very consistently are attached. A corner with no alpha at all. Or a corner with partial alpha, resulting in a solid line on top. Sometimes I get random opaque pixels as sort of a third version of this.
Capturing the white lines seems tricky at best. I certainly haven't managed that yet.
