This is still the case in Emacs 29, and I still don't understand why.

Calling flush_frame doesn't help either, or calling

	      fset_redisplay (f);
	      redisplay_internal ();

etc.  So something in tool bar seems to be hanging on to the old shapes
until...  something...  triggers a special kind of redraw.  Anybody got
any ideas?
