Following this reply, I found that there are many similar issues (which didn’t come up when I was researching initially). Two of them are linked below (thankfully, both of them have solutions, and one and the same)
Considering that it was a renderer issue, I tried logging into Gnome on Xorg, and that worked just fine. Gnome Classic on Xorg also works but not Gnome Classic. I didn’t think Wayland was this far behind in some matters. And I also should stop blaming NVIDIA Drivers for everything.
