When I click on the left fringe, the echo area says,

     <left-fringe><mouse-1> is undefined

where the foreground windowframe is regular size and immediately below
the windowframe is fullheight.

At the transition point when all frame decorations disappear in the
course of ctwm restart, it looks as though the frame translates in the
northwest direction then goes back when the decorations re-appear.

Normally, I don't use the tool bar and make it invisible, here I see the
toolbar has all button icons except for icon+save and icon+undo.

Mousing around to reproduce your observations, I found the toolbar would
flash to all buttons being icon+text when clicking on the scrollbar area
to scroll.  But at the next emacs session I wasn't able to reproduce
this glitch.

Nothing stands out as misbehaving around the scrollbars.  Normally, I
hide the scrollbar.

The following are window frame attributes before and after ctwm restart.

;; (setq-default frame-resize-pixelwise t) => t
;; windowframe is at fullheight
