-Author: Christoph Moench-Tegeder <cmt@burggraben.net>
-
-    use gdk legacy cursor interface by default
-    
-    Upstream https://bugzilla.mozilla.org/show_bug.cgi?id=1876366#c16
-    hints that we could re-test this once we have GTK 3.24.42 (with the
-    now-current gtk3-3.24.41 the original problem is still reproducable,
-    but toggling this flag does fix it for me)
