Copilot suggestion virtual text stays around with every keystroke even when typing something different than the suggestion

[GitMurf]

@AntoineGS I am not sure if these changes were the cause but I just noticed in the last day or so a weird behavior where if I am typing and ghost text appears for a copilot suggestion, it sort of "stutters" as if it is resetting the completion and virtual text. In the past I could type and it would just smoothly type "over" the suggested virtual text unless I started typing something different than the virtual text at which point it would correctly give a new suggestion.

The TLDR I believe is that we should not re-trigger the completion and/or not reset the virtual text if the suggestion is the same and still valid because you are typing the same thing that copilot has suggestion currently.

Here is a video showing what I mean:

Let me know if you have any questions.

Additionally this:

If I change the debounce to 1000 you will see a different problem which it just keeps pushing the virtual text to the side which never happened in the past. So now that I think about it a bit more, I think potentially in the past it just got rid of the virtual text on keystroke and the change related to this gh issue meant to keep the ghost text around when accepting the "next word suggestion" (which I do like by the way) is causing a problem here.

Ignore the red/green diffs as I am testing the copilot NES plugin as well right now ;-)

Ok yep, I reverted the last two commits and now it is working as it did in the past (see video)

Thanks for the feedback! This is unintended behavior and I'll look into it asap 🙂

I think I got it, I had left some code commented out that should not have been.
It probably did not help that I had to rewrite the whole feature a second time because of a weird explorer.nvim stutter that selected my root dir instead of the file I wanted when I pressed delete 😭
Let me know if the issue is resolved on your end!

The choppiness is gone so I am considering it resolved! Thanks @AntoineGS
