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

So I use an Xbox Series and their wireless receiver for the PC. It’s not plug and play for the wireless functionality, but there is a fantastic repo xone. Just clone the repo and follow the instructions and it works great.

I’m running EndeavorOS with Plasma.

I use Spectacle by KDE. Comes installed on Plasma and it’s always done a good job me.
