Dear Maintainers,

Thanks for salvaging this Gtk2 game.

The port to Gtk3 induced a regression:
the buttons doesn't show up at first,
only after having been hovered upon.


That give's a bad feeling of "Mystery meat navigation"
while trying to navigate the menu;
them ain game widget works fine.

I've got a workaround:

On a Wayland desktop, forcing X11 mode
makes everything works fine again

"GDK_BACKEND=x11 gplanarity"


Sprinkling some  "setenv("GDK_BACKEND","x11",1);" all over the place
get things done, but I'm still hoping for a proper fix

I cannot reproduce this issue.

On my machine all buttons are visible from the start.

If an app is known to work correctly via X11 but not via native Wayland,

gdk_set_allowed_backends ("x11");

is a better workaround; for example see
<https://github.com/vim/vim/commit/f80663f17b2f2499b45eb4467088704c8298c385>.
