Subwindow geometry weirdness

I've been trying to catch a picture of this bug for quite a while (well back into the 21.0 series), and now I've got it or perhaps something new that looks a little like it) on film. When VM is setting up its toolbar in the default position on the left side, messages may continue appearing in the area that used to be echo area at the bottom of the toolbar space. They will have a blank area the width of the border between the toolbar and the text windows. However, this behavior goes away once the toolbar is fully in place, so it's hard to grab with XV. The new behavior was elicited by starting XEmacs, selecting Read Mail (VM) from the menu, then I did something with the X window configuration (started the audio CD from Workman, I think it was, which popped that window up over the VM frame). In that frame (and that frame only, other VM frames started later don't show this behavior) the echo area geometry apparently never got updated; as you can see, it is overwriting the bottom button in VM's tool bar. Note how the `e' in messages is partly obliterated by the toolbar/text border. (My eyes are much too slow to detect whether that never gets written, or if it gets overwritten.) uname -a: Linux tanko 2.2.9 #4 Tue Jun 29 14:07:34 JST 1999 i586 unknown ./configure '--prefix=/playpen/gnu' '--exec-prefix=/playpen/gnu/plat' '--with-mule' '--with-xim=xlib' '--with-sound=both' '--debug' '--cflags=-g -O3 -fno-caller-saves -Wall -Wno-switch' XEmacs 21.1.4 "Arches" configured for `i586-pc-linux'.
