+Subject: [PATCH] Fix wxTopLevelWindowGTK::DoSetSizeHints if a window scale
+factor larger than 1  is set.
+
+In this case, passing INT_MAX as maximum width/height hint
+to gtk_window_set_geometry_hints leads to integer overlows.
+
+Instead, use INT_MAX / 16 which should work with all
+resonable scale factors.
