Undo/Redo updates UI multiple times per change.

[jordwalke]

When doing undo/redo, the changes are replayed line by line over several frames. There should be a single screen update per undo/redo, as if it happens with a single edit to the document, not multiple little edits very fast.

@jordwalke We're aware of this issue, and there's several issues tracking this already. #1714 and #1727 being the most relevant ones.

It's likely that we'll end up fixing this through leveraging neovim integration.

Thanks!

Oh wow, if you can use NeoVim's undo tree!

(Sorry, I searched for existing issues and didn't find those two existing ones).

Yep! That's the hope! Use Neovim undo tree, use neovim plugins, use neovim everything.

#1897 is the pr you want to follow for the progress on that.
