Its just the German word for Mother, and a nice word play of Metacity + Clutter equals Mutter.

Anyways, as always nice to have the best display server tricks on Gnome, a pleasure to use

Didn't know Gnome adopted Kwin.

My gaming experience on Overwatch at 250fps/240Hz on Gnome+Xwyland has been choppy (stutters and higher felt input lag) so far, when compared to LXQt+Open box+Xorg, on a 5700xt. Don't know if it's due to mutter or xwayland. Been trying from time to time to compare so I can use Gnome for gaming

Have you gave it enough time to fill the shader cache? Overwatch is notorious for stuttering badly until it is completely full.

For me it's virtually no difference between LXDE/OB on X11 and GNOME Shell on X11, you will always have a tons of input lag on wayland, that's why it's still in unusable state. At this point, I suspect that really can't be fixed, it seems like the wayland protocol works in such a way that adds massive amount of input lag.

I am a regular Overwatch player so my shader cache is properly populated. I think the issue I'm having lies somewhere else.

I will have to try again Gnome on Xorg and see. Although I'd like to stick with Wayland.

how about fractional scaling ?
