While investigating Wayland performance for light gaming I've noticed an
anomaly with OpenGL under Xorg which doesn't translate to Vulkan under
Xorg or OpenGL under Xwayland. With DRI3 both Xwayland and Xorg should
be similar, especially in fullscreen when compositing is disabled.

Is this a flaw in benchmark or GPU driver?
