Comment 7 for bug 1024482

@Padfoot: I'm not saying this is a lightdm-gtk-greeter bug, as I said above, it only triggers the issue. It could well be an xorg or GTK bug.

What I was saying is that if I log into Gnome with lightdm-gtk-greeter (or unity-greeter) and the cursor is set on the root window, cursor changing and resizing does not work correctly in Gnome (I was pretty sure I could reproduce it on XFCE too, but maybe I am mistaken, I will test again later). If the cursor is not set on the root window, it works as expected (with metacity or mutter, not with compiz).

I should clarify that changing the cursor theme or size does partially work, every cursor will change except the default LEFT_PTR cursor.

I posted what I found here in the hope that maybe somebody else would have an idea where to look for the actual bug.

If it does work in XFCE then that would be great, maybe I can figure out why (XFCE still uses gtk2 right? maybe it is a gtk3 bug, which would explain why it works hovering over Firefox works, though I was pretty sure I could reproduce it with other gtk2 windows too, have to test that again as well).
