Intermittently, I have a problem where I start an
C-X u. And as soon as I hit
C-p to do an undo, the
undo-tree pane closes.
This has been happening for a long while now. It happens when I use Spacemacs master or develop and Emacs 25, 26, or 27. I've even changed my keyboard.
There are no error messages in the
If I toggle the select mode, I can continue my undo to completion.
I have not been able to repeat the issue on demand. I can not determine the conditions that trigger it. Its driving me crazy.
Any idea on what it is or how I could debug this?
