Vim Muliple Cursors flashing issue!

[doantranthanh]

Hi all,

I am having problem with vim-multiple-cursors. Basically, I am using OmniSharpVim with Neocomplete so when I tried to use vim-multiple-cursors I got flashing issue. You can have a look at the gif images for me details information. I am using vim 8.0 on windows 10.

And here is my _vimrc

@doantranthanh your vimrc is way to big to be able to debug it properly. Could you please provide us with the minimal vimrc to reproduce the issue ? It should not be bigger than a few lines. We won't be able to help you without it.

Here are some questions to help narrowing down the issue:

1. when did you start noticing this issue (assuming it was working OK before) ?
2. did you read this https://github.com/terryma/vim-multiple-cursors#interactions-with-other-plugins ? You might want to try to call OmniSharpStopServer in Multiple_cursors_before() and OmniSharpStartServer in Multiple_cursors_after()

[doantranthanh]

Thanks for your supports!

I have try to stop Omnisharp but nothing changes. Then I just recognized that I am using conemu to run VIM , therefore I tried to use GVIM and GVIM works beautifully with all plugin. So I think the problem might be from ConEmu terminal. Let me try to fix it. But in the time being, if you have any pieces of advice then please support and share with me?

Many thanks

[antoinemadec]

Glad to hear that :smile: Sorry, no, I never heard of ConEmu before.

I am closing that issue. Don't hesitate to add the solution when found or to re-open the ticket afterwards if needed.

Cheers!

Hi Antoin

It is an alternative terminal of cmd on Windows. Unfortunately, it does not support gui I guess. I tried to fix but no luck so far. Will do it again and update the solution.

Thanks
