Extremely slow when typing (limited to a special row)

[thomai-d]

Describe the bug Typing in this particular line is extremely slow if the vim-plugin is activated. It's only this particular line. Every other codelines work fine.

To Reproduce

1. Open the attached file and type "required [(ngModel)]="amount" at the end of line 18 without vim plugin installed => Everything is fine
2. Install the vim plugin (1.0.8)
3. Restart vscode
4. Repeat step 1

Expected behavior No delay when typing.

Screenshots

In the video, I'm typing as fast as without the plugin, but there is a huge delay between typing and the characters showing on the screen. When I'm circling the mouse around the cursor position, I'm already finished typing for a few seconds but the character appear slowly one after each other.

It's only in this particular file (attached) and online in line 18. But I can reproduce the problem on another PC, too.

Environment (please complete the following information):

• Extension Version: 1.0.8
• OS Version: Windows_NT x64 10.0.17134
• VSCode version: 1.31.1

Running into the same thing when editing a large JSON file. Disabling the vim extension sped things right back up.

I've been running into similar issues. It only seems to occur when editing long lines of JSX, wrapped inside a switch statement, and I'm typing inside an attribute. The latest culprit:

switch (status) {
  // snip
  case Status.LOADING:
    return <Loading title="Loading subscriptions..." body="Please wait. Fetching your subscriptions from the r" />;
  // snip
}

The longer the line gets, the more it lags, and eventually the extension host crashes. I can add more if I wrap the JSX element across multiple lines so it doesn't get so long. But it's still a bit of a pain.

I've experienced the same problem across 4 separate machines. I don't know the exact versions on the other machines, but my current one:

Extension Version: 1.11.2 OS Version: Ubuntu 18.04.3 LTS (Reported as Linux x64 5.0.0-31-generic snap in VS Code About) VSCode version: 1.39.2

Anyone have a fix for this? When it starts lagging for me it usually takes about 10-20 seconds to render a single character. I do notice it happening a lot when working with JSX
