Cursor jumps few lines up, when hitting tab to complete.

When I type cd then hit Tab to view suggestions, the cursor suddenly jumps few lines up.

• ZSH version: zsh 5.4.2 (x86_64-apple-darwin17.0.0)
• OS information: macOS 10.13.1 (17B48)
• ZSH version: zsh 5.4.2 (x86_64-apple-darwin17.0.0)
• Terminal program & version: iTerm Build 3.1.5.beta.2, same in Terminal.app
• Operating system: macOS 10.13.1 (17B48)
• ZSH framework: prezto

Regarding pure versions:

I can confirm the issue appears in 4cdd0cf.
Before that commit, it's ok.

At first I've reported it to prezto, but looks like problem in pure theme.

So far I've checked out to tag v1.5.2, as workaround.

Have you tried master? If not, could you? This commit might fix your issue a3b22b2. Keep in mind this also requires the latest zsh-async, so you might need to update that as well.

Switching to master a3b22b2 didn't help. How do I check/update zag-a sync?

[mafredri]

Sorry, that was supposed to be zsh-async (not zag-a sync), thanks autocorrect.

[vbauerster]

The issue still persist, despite prezto framework has upgraded zsh async module to tag v1.6.0 recently.

Alright, then I believe #362 could be related. Can you try the suggested workaround in #362 (comment)?

[vbauerster]

I confirm commenting out expand-or-complete-with-indicator have fixed the problem.

[mafredri]

Ok, that's great (and bad) news. Great that we know how to avoid it, but bad as in I don't have a solution for this. The problem likely stems from the fact that Pure is a multi-line prompt (includes newlines in $PROMPT) and prezto is calling zle redisplay while completion is active. I believe this state confuses ZLE and might actually be a bug in Zsh (e.g. cursor outside editing buffer and prompt is multi-line).

EDIT: The reason reverting to v1.5.2 fixes the problem is that Pure was not yet a multi-line prompt back then, just a single line prompt where we handled the preprompt part manually with terminal codes.

This should now be fixed, as per sorin-ionescu/prezto#1512.
