Thanks for taking a look.

My patches are for fixing mupdf-gl (the GLFW created OpenGL viewer).

desktopConfig, which is what I use in my extended version of
example-config.hs, has basic EWMH enabled. Nonetheless, I've added
handleEventHook with EwmhDesktops.fullscreenEventHook, but it didn't
make a difference.

I think you tried the x11 viewer and not glfw. Test mupdf-gl instead.

So, if you manage to modify

https://raw.githubusercontent.com/xmonad/xmonad-testing/master/example-config.hs

such that it doesn't (on entering fullscreen) print a set of

gl error 65544: X11: Iconification of full screen windows requires a
WM that supports EWMH fullscreen

and thereby toggles fullscreen like mupdf-x11, we can fix the example
config.
