Cursor move delay on change command

Originally posted here

Sometimes, when I go into insert mode with something that modifies the buffer length (ie change commands) and start typing too fast, the cursor does not update fast enough and it inserts text in the wrong place. For example, here I type ciwadditional but this happens: I am on the latest commit of this branch.

This problem still happens with an empty init.vim and all vscode extensions disabled. Here, you can see the first time it ignores the “j”, and the second time it places “j” in the wrong spot after the cursor. I have slowed the gif down by 50%.

Edit: The more vscode plugins I have enabled, the worse the issue becomes. With all extensions disabled like above, the issue only happens 30% of the time, and usually with only one or two characters. With all extensions enabled, the issue becomes as bad as in the first screenshot.

it should work fast at least with untitled file. curious

Well, i have 2 possible solutions here. Won’t mind to try both ? i’ll compile two PRs soon

Sure. I can easily compile myself as well if that saves you a step.

And yes it is very fast, it took me 10 tries to repro.
