Video of issue
Here is the video of the issue
Thanks for the video. I guess we need to wait until someone else can confirm this issue. From my side I cant reproduce it as I don't have an AMD GPU.

I can confirm this issue, I have both intel graphics and nvidia, but plasma runs on the intel card. I am also on arch linux. In addition to the behavior listed, sometimes the desktop also just stays black and there will only be rendering within a buffer around open windows. and taskbar widgets. Meta + D to the desktop fixes it immediately, presumably since it triggers a redraw. If I sleep my laptop by closing the lid and opening it, I can actually see the black background issue before even SDDM opens up (I think that is another bug, as for privacy/security concerns you shouldn't be able to get a glimpse of plasma on resume before SDDM takes over). Note that I am running both SDDM and plasma on Wayland. Ah, I think I have some additional info. When I said sometimes it just stays black, it seems that that was because the mouse was moving. In fact, I've found out that it starts flashing as the mouse is moving, and stops flashing and will either stay on background, or black screen, as the mouse move stops. It is still solved by force showing the desktop with Meta + D. As a game developer I'm taking a guess here and saying that it might be a frame buffer issue, with one of the framebuffers not being updated with the desktop background - probably because of vsync?
