I put a break on x_clear_frame, and with emacs -Q, byte-compile-file on scheme.el triggers it. > (while t > (split-window-below) > (sit-for 0.05) > (delete-other-windows) > (sit-for 0.05)) > > Typing "C-x C-e" at the right paren of this in *scratch*, I see no > flickering in the tool bar. Do you? Oh yes. It looks awful! In an attempt to follow your instructions, I put a break on dispnew.c:3045. So far I don't think I am getting any useful information out of this, because it seems to trigger a lot, and I'm not sure I'm catching it at the right time. I'll try again later, but frankly I don't know what I'm doing, even with your detailed instructions. Here's current_row and desired_row in update_text_area one time.
