VS code suddenly very slow

[Pibe97]

Type: Performance Issue

From one day to another, vs code has become super slow and I am not sure why. The same issue persists when I disable all extensions.

VS Code version: Code 1.90.1 (611f9bfce64f25108829dd295f54a6894e87339d, 2024-06-11T21:02:43.666Z) OS version: Linux x64 5.15.0-87-generic snap Modes:

I have the same problem:

I downgraded to 1.89 and that seems to fix the issues. Apparently it is the 1.90.1 update that makes everything super sluggish. Lesson learnt: disable auto-update.

Can you please share a performance profile as per https://github.com/microsoft/vscode/wiki/Performance-Issues#visual-studio-code-is-sluggish ?

Would love to, but in my case VS code crahses when I try to use the developer tools.

Same here!

Can confirm that downgrading to 1.89 solves the issue. Maybe auto updating is really a bad choice...

Looks like you're using the snap. Duplicate of https://github.com/microsoft/vscode/issues/212494.

Fix should be coming in the next day or two.
