First, let me say AWESOME VIDEO. You took the time to film it right, and it shows!
Consider VRAM a cache. The point of it is to house as much frequently accessed data in there as possible, to maintain optimum performance. It can not be used by you directly for anything else anyway so there is no point in keeping it empty. The usage varies based on screen resolution, the needs of the apps or games currently running, and so on.
There's no question that it shouldn't be there, but I implemented the workaround and I don't see any white line glitching. As for the corners, I need a magnifying glass to see it. The corner glitch you are referencing is an extra 50 pixels in the upper left corner of some windows. Can't see it. A spec of dust is bigger. To see this problem you have to open specific app windows and then move them up or down one pixel at a time until the issue manifests itself. To verify that it actually occurred I would need to press my 51-year old eyes up close to the screen. That is the definition of a non-issue to me.

I get your point and mostly agree. And not to argue this further needlessly but: if you had other non-visible (to you) issues with your hardware or software... and if those later developed into more visible problems... say freezes and random crashes (which tend to result from faulty video card hardware and/or software), you would call them non-issues until you were fully impacted? I am simply saying that it worries me quite a bit that my video card is not behaving correctly and that at some point I may need to try to get it fixed by Apple (in our newly formed and slowly moving Covid-19 world nonetheless). That will cause me downtime, loss of income, and I am sure a headache or two. Yes, I have ways to mitigate that but it is still a concern. I wanted to trust Apple to deliver a quality product. They have before and I have come to rely on that (foolishly, yes).
I've seen the line glitch happen in an active Photoshop window as well as Word and possibly other applications.
I think if there was something troubling with the graphics card then we would see it show up in the benchmarks as well as in real-world situations (rendering, gameplay, etc.). The fact that it doesn't show under Bootcamp is comforting about it not being a hardware issue.
Doesn't attaching a 2nd display eat into your TB3 bandwidth?
I definitely understand how the graphical glitches being minor make it feel like a minor issue. I care more than I should about the roundness of round-rectangles, but the real concern is whether I can trust the GPU to render anything correctly. If I’m doing graphic design, web design, photo or video editing, I could be seeing and working around a visual artifact that isn’t really there.
I think we all agree here!
Dunno. In either case, that’s how I’ve always planned to use the computer so it’s mostly irrelevant to me. The added bonus of not losing my mind like some have makes it even better.
Spot on.
You should add a secondary DNS like AdGuard DNS to your settings just in case your Pi-hole goes down again.
