francesco, I think the reason you find Xorg is more fluid might be because you're using two GPUs (Intel + AMD) and mutter's Wayland handling of secondary GPUs is sometimes inefficient. To prove that is the issue, you can try unplugging the external monitor(s) and just compare the laptop screen performance in Wayland vs Xorg.
