Re-enabling them once at the first repaint (out of the resize handler)
*might* work, depending on how Gtk keeps its state. If the WM is
ignoring hits, we would be disabling/re-enabling Gtk hints at each event
when "live" resizing, though.

I would need to try or read Gtk sources to be sure. Maybe Gtk has some
synthetic events that we could use.

If not, leaving them disabled would still be a better option.
