What OS are you on? And have you attempted to change the rendering system?
i tried using all the rendering systems, im on windows 11I know on Win11 there is a transparency setting that exists for screens that could overwrite my own, but I don't know it off the top of my head. Do me a fav and open the terminal (~ key) and type config
Head to that location and grab your logs and upload them somewhere like Google Drive for me to look at. Maybe there is an error happening.
