GNOME & KDE Plasma Wayland Sessions Outperforming Xfce + LXQt On Ubuntu 25.04 For Linux Gaming

Last week I posted some initial GNOME 48 and KDE Plasma 6.3 desktop gaming benchmarks on Ubuntu 25.04 beta for looking at the performance of those two leading desktop options for this upcoming Ubuntu Linux release. Both GNOME and KDE under Wayland were outperforming KDE on X11 (and GNOME on X11 wasn't even working due to bugs). Some Phoronix readers questioned though whether the Wayland advantage on GNOME/KDE was due to those desktops losing focus on X11 support or if they are just too bloated. So for adding some additional context, here are some graphics/gaming benchmarks on the same system hardware/software when adding in the Xfce 4.20 and LXQt 2.1 X11 desktops.
