windo work to popup buffer and error?

Thanks for reporting. It seems clearly quick-hl's bug.
It should be able to fix by detecting a popup window and ignore it.
If someone can fix it, I really appreciate it. I have not much time to work on this in the next 1.5 months.

I believe the above commit fix your issue.
I am not an active vim user now and I do not use an async complete popup, so I could not reproduce your issue in my setup.

My fix is technically read manual and theoretically applied what I believe I can fix.

Please give feedback to me when you tried.

I noticed my misunderstanding for window-ID, so the above code does not fix your issue.
Let me find proper way.

I believe this is it!
Please give feedback when you tried.

Thanks a� lot.
try it

I try it.

result:
Error happen.
message as same.

(note: Currently completion work vim-clang)

I re-try it.

error occur.

I think execute in normal(not popup) window, win_execute is usable?
see https://vim-jp.org/vimdoc-ja/eval.html#win_execute()

(error E994 is https://vim-jp.org/vimdoc-ja/eval.html#E994)

3rd try it.

It OK, do not happen error E994 and popup appear.
