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.
