Anyone else experiencing cursor flicking in nightly?

After update to recent nightly:

Seems caused by:neovim/neovim#31562 and surprisingly so far I only experience this issue with 'find files', e.g. find commits does not flicking.

I’ll check if there’s something that can be done from fzf-lua’a side about this.

Thank you!

And I just tried with mini.sh, same behavior.

It has cursor blinking by default (which introduced by the PR I mentioned), a bit hard to notice but you can still see sometime when delete a char, the cursor and the letter overlap.

My first guess would be something related this change (mentioned in that PR):

since terminal windows now use the real cursor

Another interesting behavior is that when select an entry, the cursor will reposition to beginning (maybe always do? but at least in the older neovim I cannot notice).

Do you have line numbers/columns in your grep output. Does the preview show the column?

[RayGuo-ergou]

Yes I do.

[ibhagwan]

Yes I do.

No, I meant in grep, some users remove --column and then don’t have line/columns in their grep output so fzf-lua doesn’t know the line/col, when switching between buffers/files it shouldn’t move the cursor.

I am using ripgrep and did not change rg_opts in config

I am also seeing this in lazygit's commit input, I think it's related to neovim itself or the terminal emulator.

Sorry for the false report.

So I looked into it, the merged PR you linked neovim/neovim#31562, it basically proxies your current terminal cursor to neovim, from my short testing the flickering depends on the terminal type, different on alacritty, wezterm, windows term, etc).

The good thing is that the PR also adds another terminal mode setting t in guicursor so you can control this behavior.

If you wish to restore the previous non blinking block cursor:

:lua vim.opt.guicursor = "n-v-c-sm:block,i-ci-ve:ver25,r-cr-o:hor20,t:block"

If you want a vertical line (similar to INSERT mode):

:lua vim.opt.guicursor = "n-v-c-sm:block,i-ci-ve:ver25,r-cr-o:hor20,t:ver25"

I'm considering making one of the above the default with fzf-lua but I'm not yet sure about it as guicursor is a global setting meaning I would have to set and restore it.

[RayGuo-ergou]

Thanks for looking into it! I’ve already disabled the blinking cursor ( I set to n-v-c-sm:block,i-ci-ve:ver25,r-cr-o:hor20 which should do the same thing), but the issue is that the cursor isn't as smooth as it used to be. For example, when inputting or deleting characters, or navigating through options in the file list, I can see it flickering abnormally.

It’s not very noticeable, and in fact, I haven’t noticed it at all in the past two days unless I think about it. I think I can live with it :-).

Thanks for your time and have a good holiday! 🎄
