c++ program demonstrating issue

Fullscreen windows created via SDL_CreateWindow() using the SDL_WINDOW_FULLSCREEN_DESKTOP flag are not visible when run in xmonad window manager. This also occurs to a window is set to fullscreen via SDL_SetWindowFullscreen(window, SDL_WINDOW_FULLSCREEN_DESKTOP).

Attached simple program demonstrating issue.
Comment 1 Lucian Poston 2015-11-14 09:49:42 UTC 
For anyone else encountering this issue, a workaround in xmonad is to enable ewmh. See http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Hooks-EwmhDesktops.html#v:ewmh

Enabling ewmh causes libsdl2 to use _NET_WM_STATE_FULLSCREEN code path instead of the legacy mode in SDL_x11window.c.
