Simplest way would be to open a term windows and type ‘ps aux | grep Xorg’ minus the quotes and hit enter. Ignore the output that has grep on it. Examine the output. If only one line, then you are most likely on wayland. There are other ways, but we would need to know more about your system.

What cards and wayland compositors/xorg are you using? I have a 4080 and am on plasma 6.3 and don’t have any graphical glitches with steam.

I agree. There are times when I speak to someone that has an unfamiliar accent that my brain has trouble processing. They can be speaking fluent English , but I still struggle.
