you are using arch i assume by the depth of your explanation. anyway, a short google for wayland + second monitor + flicker alone yields a plethora of results. i can say it does not work for me.
I am on kubuntu and on a intel igpu. The search results mostly read arch plus nvidia as a bad combination. Perhaps or probably i just got lucky with my hardware.
