> Try submitting a bug about how menus are displayed 5px from where they are supposed to be in a GTK app rendered on a X11-server that runs on the Windows desktop and see if the GTK developers care.
This one sounds so specific that I suspect you must have a reference to a bug tracker or a mailing list message somewhere. Do you? Having the context of the whole interaction is helpful when forming conclusions.
Without the benefit of such context, I'd suppose that the effort of reproducing the bug (not everyone has a Windows machine handy; the X11 server might be commercial or obscure) is a petty good reason for not giving it more attention.
