Missing wallpaper - possible graphics issue?

Right, I’m having issues pinning down exactly what is wrong here other then it seems graphics related, so bear with me:

Recent install as a dualboot with Win11 (issue is specifically on the EndeavourOS side, just for context) on a Aegis R 14NUE7-680US w/ Core™ i7-14700F RTX 4070 SUPER computer, with two monitors. The graphics have been… temperamental.

The clearest current manifestation of this is the wallpaper on my main monitor has gone missing, and is now just a black screen no matter what I do (trying to change the wallpaper, resetting, etc.) - this isn’t the case with the second monitor, which is not having this issue. The main monitor otherwise seems to be functioning.
I’ve also been getting some other graphical issues - XIVLauncher-RB causes both itself and the entire display to reset repeatedly until it fully loads, and I have a Reshade install that crashes when loading effects seemingly due to something with the graphics according to the log(but it functions fine if I get it to load, it’s just loading new effects), as examples.

I have Nvidia drivers installed visa nvidia-inst, they are up to date and correct to my knowledge (550.90.07), and otherwise seem to function fine - Steam and games through Steam generally work fine, etc.

KDE Desktop, X11 (Wayland gave me other issues).

I did xprop both of the monitors, hidden for space:
