Another very interesting observation: I added back my Xorg configuration and SDDM starts without a cursor (even if I move the trackpad), the cursor is there it's just not being rendered, when I log in then I get the black elements in Plasma. However, if restart,change to a tty before logging in and restart the sddm service, the problem is fixed, I get my desktop and I can use PRIME Render Offload as intended.

Note that this is not always the case. Sometimes I just get a black or garbled rainbow mess on the screen, in that case I c¡have to power off the computer let it rest for a moment and then I can continue with the same procedure.
