I remember that weston-simple-egl -f was broken when using software
rendering in mesa. From my irc log:

21:56:01< rawoul> 'weston-simple-egl -f' is also broken with
LIBGL_ALWAYS_SOFTWARE=1 on libweston-desktop... That's a mesa bug
though, the first commited buffer does not use the size sent in the
configure event
22:02:04< SardemFF7> not sure it’s a mesa bug
22:04:32< SardemFF7> mesa doesn’t know about the shell protocol, and
that’s a requirement from xdg_shell_v6
22:05:16< rawoul> SardemFF7: the client does properly calls
wl_egl_window_resize with the correct size before the first call to
eglSwapBuffers. It actually works with dri2, but it seems swrast
defers the resize
