Function completion popup writes remnant artificats to buffer

[perks]

Usually occurs when using tab completion, for example see below

=`=jedi=0, =`=                            (arg1, arg2, *_*arg3*_*, arg4='patch', arg5=None) =`=jedi=`=

All over the line.

What happens is once the line is finished editing, a particular argument becomes highlighted (in this case arg3).

Upon first inspection it looks like the line is fine, however upon "selecting the line" (movement to the line in normal mode) the screen changes and above text is replaced in the buffer.

The function being called look something like this:

    def helper_func(self, arg1, arg2, arg3, arg4='patch', arg5=None):

This isn't a visual bug either, it actually leaves text in the buffer, usually resulting in having to undo/rewrite the line (I catch it because it usually breaks my makefile)

I remember having fixed something in this regard, but could not find it now (I am on mobile).
IIRC there are cases where we cannot really prevent it.

A test case would be great.
IIRC there should be something in the got history of "tests" regarding this.

See #412 about a workaround, and leave a vote in case you think the default should be changed.

I ran across this issue today.

appeared when I cd into a directory through NERDTree plugin in gvim and opened a few files for editing, both python and plain text.

Surprisingly didn't appear in single edition of one py file with usual :cd beforehand, and I cannot reproduce it now.

If someone wants to investigate, maybe it's a starting point. In any case I’ll keep you informed if I can reproduce.

I have a similar issue of jedi-vim leaving function signatures in the buffer, here is a screenshot. The cursor just typed the .. I haven't hit tab or anything like that.

It happens to me as well but very rarely and I'm not sure if it just happens if something bad happened before and jedi-vim basically "crashed".

It only started after a recent upgrade, though I don't know what revision I was on and subsequently upgraded to. I am not a Vim ninja when it comes to debugging, so any suggestions on how to help find the issue, I am all ears and would be happy to help.

My vimrc is here: https://github.com/nZac/dotfiles/blob/35f97b06b46db8f85a2181df258a67f0a88e87ec/vim/vimrc.symlink if that is helpful.

I suspect it has something to do with python3 annotations. I encountered
the bug again with an annotated function, but not with the completion for
other function in the same script, which were not annotated.

It seems to happen more and more :/ It's not about python3 annotations, I'm not using them.

I have a minimal example that reproduces this for me 100%. Seems to happen when using completion inside calling another function.

Actually I think I had a typo in my conf - for some sill reason I'd put quotes around my "2" in show_call_signatures.

Upon testing a bit more, it seems that show_call_signatures = 1 gets rid of it and show_call_signatures = 2 brings it back. Very odd.

[davidhalter]

Strange. 2 should do something completely different and not even touch the viewport (but should change the statusline).

[blueyed]

And for the missing conceiling with 1, make sure that the after part of the plugin gets used - which should typically be the case when using Vundle/syntastic etc, but might get missed when manually manipulating &runtimepath.

@dpnova The tutorial in README file of this project does put quotes around the value of show_call_signatures...
