No idea if it will help you here, but everytime someone mentions to me they are having display output issues and they’re using Wayland and an Nvidia GPU, I recommend trying X to see if problem persists or not. If it doesn’t, I would suspect the GPU driver, but that is a VERY uninformed guess. Lol

As a software dev, I have spilt coffee on myself a number of times. People just don’t understand what a hard working environment it is. 😞
