Plasma, Wayland & NVIDIA Proprietary Drivers giving issues

When I began having issues with choppiness a few months back, I thought I had troubleshot all software possibilities, which led me to conclude that it was a hardware issue.

I tested every piece of removable hardware (graphics card, power supply, etc...) and determined after all of that, that it must be the processor itself, and so bought myself a new (to me) computer.

After reinstalling everything, this new computer is doing the same thing, and I realized that there was one very important thing that I never originally checked...the compositor.

And it seems that, somehow, that is the issue, but I'll be darned if I've been able to figure out how to fix it.

Tried on 3 different distros (Manjaro, CachyOS, Neon)

Somewhere between Wayland, Plasma 6, and the NVIDIA Proprietary drivers, things are glitching out. Everything works fine under Nouveau, but of course that keeps me from being able to do more heavy lifting like Blender, Resolve, etc...

Tried the Proprietary drivers both from within the distros themselves and directly downloading and installing the drivers from the NVIDIA website.

Back when the trouble first began and I was working under the assumption that it was a hardware issue, I tried multiple power supply units to no effect. I then tried using an older NVIDIA card which gave the same issue (Nouveau Good/Proprietary Bad). Reset and later replaced the RAM.

While I slowly work my way through the Arch pages regarding NVIDIA drivers, I figure I may as well ask if anyone has had success fixing glitches between Wayland, Plasma, and NVIDIA. Research says that such glitches are apparently pretty common with the newer versions of plasma. Looking for any tricks I may not have found yet.

Thanks

Edited - And no, switching to AMD just isn't in the cards right now. I barely had enough scraped together to get a used desktop off of Ebay. There no chance I'll be able to afford an AMD GPU equivalent to my GTX 3060.
