Vim: Switching Vim Modes (insert, visual, etc) will hang VsCode

[jwmann]

Describe the bug
In the most recent version of VsCode, switching modes will result in a hang.
This happens regardless of the mode switch, visual or insert or back to normal mode.
Setting "vim.statusBarColorControl": false, will alleviate the issue.

To Reproduce

1. Have "vim.statusBarColorControl": true, in settings.json
2. Switch to a different vim mode (e.g.: press i in normal mode)

Expected behaviour
No editor hang

Environment (please complete the following information):

• Issue Type: Bug
• Extension Name: vim
• Extension Version: 1.8.1
• OS Version: Darwin x64 18.2.0 (MacOS 10.14.3)
• VSCode version: 1.36.0

This is related to #3825

Getting this as well:

• Extension Version: 1.8.1
• OS Version: macOS Mojave 10.14.5 (18F203)
• VSCode version: 1.36.0

Confirmed setting "vim.statusBarColorControl": false alleviates issue.

Yeah, it is quite heavy to have the Vim plugin edit the settings.json file and make VS Code re-fresh settings every time you switch modes.

Is there not a better way? Why doesn't the plugin instead trigger styling for a CSS class that targets the status bar, instead of modifying settings.json?

Getting this with Windows 10 as well.

Extension Version: 1.8.1
OS Version: Windows 10 Enterprise 1903 (Build 18362.175)
VSCode version: 1.36.0

Can also confirm that setting "vim.statusBarColorControl" to false removes the lag.

There is a disclaimer on our readme for this feature. Please see the linked issue for more background information: https://github.com/VSCodeVim/Vim#vim-airline

Tracking down what was causing this slowdown was rough. I turned this on a long time ago and never had issues until recently. Thanks for reporting!

[jwmann]

@jpoon Thank you for pointing that out, however I already knew this feature came with a performance hit.

I have been using this feature for roughly 6-7 months now. As soon as VsCode updated to 1.36.0 it has made the editor become practically unusable. I'm talking a full 2 second hang after every mode switch vs maybe an extra millisecond from before.

The difference is night and day.

I encountered this when going to insert mode and typing a period. It was not set in my json file to anything.

Extension Version: 1.8.2
OS Version: OSX Mojave 10.14.6
VSCode version: 1.36.1

Confirmed manually setting "vim.statusBarColorControl": false alleviates issue.

----- UPDATED ----

Turns out this didn't fix the issue. It fixed the issue if I type a period, but it now hangs when I type a quote.

----- UPDATE -----

disabling the extension...

IntelliSense for CSS, SCSS class names in HTML, Slim and SCSS

...seems to have resolved the issue.

Guys, guess we have to ask the VSCode team for a proper API to change status bar instead of the current hack? I'm currently experiencing huge lag about 2~3 sec when switching mode or search which insane.

Just to add to the pressure, Vim plugin for Visual Studio Code has become unacceptable in the last months. I type fast, and I constantly get scrambled letters because Vim creates huge latency in responding to commands.

Looks like I was blaming it on Vim plugin when actually the "Auto Import" plugin was slowing down my whole Visual Studio Code. Sorry, it wasn't intentional. After uninstalling Auto Import, I still have auto suggestions, Eslint, and Vim Plugin, but no more abnormal slowdown.
