This section of code is in gdkkeys-x11.c and called from update_keymaps:
mask = 0;
for (j = 0; j < keymap_x11->keysyms_per_keycode; j++)
{
if (syms[j] == GDK_KEY_Meta_L ||
syms[j] == GDK_KEY_Meta_R)
mask |= GDK_META_MASK;
else if (syms[j] == GDK_KEY_Hyper_L ||
syms[j] == GDK_KEY_Hyper_R)
mask |= GDK_HYPER_MASK;
else if (syms[j] == GDK_KEY_Super_L ||
syms[j] == GDK_KEY_Super_R)
mask |= GDK_SUPER_MASK;
}
Which seems like it accepts the GDK_KEY_Super_L/R and subsequently sets
the mask, right? I believe this is the reason why the virtual mask is
recognized when using Xwayland on wlroots based compositors.
