Dear Maintainer,

Under GNOME (Wayland), running i3lock works okay until you hit the MENU
key (the one that shows all the windows spread out and small, but with
all their glorious content clearly visible albeit dinky) at which point
one can look at what's displayed in the windows, or kill a window, or
even pull down a menu and pick something naughty.

Cheers,

On first glance, this sounds like an issue with XWayland, so possibly this
issue needs to be re-assigned.

Note that i3lock is not tested under Wayland at all, and won’t be for the
foreseeable future. Please use a screenlocker for Wayland instead.

compositer proper.

Maybe there is an easy way to do this that X11 locking apps could
tickle; I know "xdg-screensaver lock" somehow manages, perhaps the
code could be broken out from there. But the current situation could
lead to users *thinking* their screen is locked securely when it isn't
really, so even some stopgap measure might, I think, be reasonable to
consider.

Pull requests or hints in an upstream issue (at https://github.com/i3/i3lock)
to improve the situation are very welcome :).
