Howto eliminate flicker?

[tmpm697]

Describe the bug Vim uses lazydrawn to renew screen somehow that cause flick.

Environment:

• OS: archlinux
• Vim version: latest git
• This plugin version: latest

Vista info

    Current FileType:
Avaliable Executives: ['ctags', 'vim_lsp']
    Global Variables:
    let g:vista#executives = ['ale', 'coc', 'ctags', 'lcn', 'nvim_lsp', 'vim_lsc', 'vim_lsp']
    let g:vista#extensions = ['markdown', 'rst']
    let g:vista#finders = ['fzf', 'skim']

Steps to reproduce given the above info

1. open a file with tags (from ctags)
2. move around between tags
3. observe cursor change from vista when moving cursor between tags
4. sometimes when you stop cursor at some point, it does flick

Expected behavior Does not have flick

Actual behavior less flicks than tagbar but still flick at some points.

Not sure what the flicker is.

@liuchengxu I'm seeing this same flickering behavior. It occurs on file save or if the TextChanged and TextChangedI events are enabled. Could you please reopen? I can provide more information if needed.

[ranebrown]

It is definitely related to the screen redraw. I am seeing the same thing when switching windows from the vista window back to the main window. The behavior is much less noticeable with a minimal vimrc but still present.

Can't help more with the current report.

[tmpm697]

Is that possible to have external binay running in background causing this issue? I think ctags binary is running in background and might produce the issue. I observe the same behavior when using linter/fixer from ale.

[ranebrown]

I would definitely like to get this fixed as it is making vista unusable for me but not really sure how to figure out what is causing it... I'm more than happy to do some troubleshooting if you point me in the right direction.

I have screen flicker problem in vim too.

[tmpm697]

Either one or more plugins are using/calling binary in background that cause this issue, you can open nvim with each one of them to figure out, or check this if you use tmux.
