Thanks.  

Would you please instrument emacsgtkfixed.c like such:

diff --git a/src/emacsgtkfixed.c b/src/emacsgtkfixed.c
index 2b6ebee65fd..24aaf134dd2 100644
--- a/src/emacsgtkfixed.c
+++ b/src/emacsgtkfixed.c
@@ -178,6 +178,9 @@ XSetWMSizeHints (Display *d,
 	 data[5] = w;
 	 data[6] = h; */
 
+      fprintf (stderr, "XSetWMSizeHints: %d, %d\n", hints->width_inc,
+	       hints->height_inc);
+
       /* Make sure min_width and min_height are multiples of width_inc
 	 and height_inc.  */
 
and tell me what is printed when Emacs begins to shrink?
