No, this shouldn't be an issue. The check for Gnome is that we see
whether the atom "_WIN_SUPPORTING_WM_CHECK" is set on the root window.
This has been replaced by "_NET_SUPPORTING_WM_CHECK", which is the EWMH
way to do the same. The Gnome setting is only a fallback for very old
Gnome systems.

That said you could try to find out which values setwindowlevel: is
setting on your machine for tool tips and what would be the correct
ones. You will need to add your own logging for this.
