From my own experience over the years using different distris, all graphical glitches mostly boiled down to Nvidia graphics. It made me distro hop aimlessly for a long time 
I never had an RTX though, and switched to AMD in the meantime. Also nvidia did not work well with wayland in the past, now maybe better, but you can also login using x11 to see if glitches persist.
I mostly game on Steam Deck so I wont be much help, but seems you have a very nice hardware setup. If you look for solutions this forum is great. Once you install EOS, you can post logs and better infos so people can help. Else its a bit difficult guesswork for troubleshooting. Its a great place to learn here.
Using the newer drivers might help.
