bug#36680: 27.0.50; undo-tree visualizer flickering with display-buffer-

From: Michael Heerdegen
Subject: bug#36680: 27.0.50; undo-tree visualizer flickering with display-buffer-reuse-frames -> t
Date: Tue, 16 Jul 2019 00:23:30 +0200


recipe from emacs -Q, after getting a source of undo-tree:

Copy to scratch and evaluate

(setq display-buffer-reuse-frames t)
(require 'undo-tree)

Make some further edits to scratch for testing.  Then

C-x 5 2
C-x u

Any time you switch the current node in the visualizer, the first frame
is raised for a very short time, then lowered again.  This is quite
annoying, it makes C-x u quite useless when you have a window in another
frame displaying the current buffer because it distracts me from seeing
what changes in the buffer, I'm unable to see it.  Setting
display-buffer-reuse-frames -> nil fixes this.

The visualizer calls

  (switch-to-buffer-other-window undo-tree-visualizer-buffer-name)

which doesn't seem to behave well in this situation.
