Vscode: Intellisense Unusably Slow

[keegandonley]

Issue Type: Performance Issue

Even with all extensions disabled, Intellisense and autocomplete are now too slow to be useful

VS Code version: Code 1.33.1 (51b0b28134d51361cf996d2f0a1c698247aeabd8, 2019-04-11T08:22:55.268Z)

Happy Coding!

Downgrading to 1.30.1 solved this for me fyi @keegandonley while this get's sorted out.

@mjbvz Issue is persistent no matter what I try - rebooting, reinstalling, or disabling plugins. Happy to provide more information if you let me know what will be useful; I did include all the system/workspace information from the bug reporting tool in VS Code.

@scottmeschke downgrading solved for me as well, thanks for the info

What language are you working in and what is the basic structure of your project? Does this happen in all workspaces, or just one in particular?

Also, does this reproduce in the latest VS Code insiders build with all extensions disabled?

[roniemeque]

Can confirm I started having the same issue out of nowhere. Fresh install didn't work, going back to 1.30 solved the issue for now.

Closing as there is not enough information to investigate this. My best guess is that this is duplicate of https://github.com/microsoft/TypeScript/issues/31302 but please share repo steps and information about your project to confirm
