General lagging and high cpu usage #215512

Closed hp-peti closed 4 months ago

hp-peti commented 4 months ago

Type: Performance Issue

Just trying to use the environment for regular work. Editing any kind of text file or even typing into the top bar is lagging and generating high cpu. Scrolling is also choppy, especially with custom views such as the popular Git Graph extension.

I have observed the issue in VS Code Insiders a couple of days ago to the point i stopped using it. VS Code Dev (online) and previous version (rev 160) did not suffer of this problem.

VS Code version: Code 1.90.1 (611f9bfce64f25108829dd295f54a6894e87339d, 2024-06-11T21:02:43.666Z) OS version: Linux x64 6.5.0-35-generic snap Modes:

This also happens to me. It makes all my 12 cores go to 100% when I select text.

This is likely related to the workaround in #212494 being implemented as a temporary fix to crashes on startup with the snap package. Since the issue was only partially resolved, it is recommended to revert to 1.89.1/snap revision 159 since that avoids the crashes or to switch to the debian package until the issue is resolved.

Please revert to v1.89 or use debian package till this issue is fixed. https://github.com/microsoft/vscode/issues/212494#issuecomment-2166941209

Snap revert: 

sudo snap revert code --revision 159

Properly installing debian package with signature checks working can be found in this comment: https://github.com/microsoft/vscode/issues/212494#issuecomment-2119250968

Duplicate reports so far:

AvesekShrestha commented 4 months ago

This also happens to me. Lagging when typing and scrolling

nadar commented 4 months ago

Same!

Snap revert:

sudo snap revert code --revision 159

error: cannot revert "code": cannot find revision 159 for snap "code"

Instead, the following revert command without a specific version worked for me:

sudo snap revert code
RicardoM17 commented 4 months ago

Same here, running 1.90.1 as well. Everything was perfectly fine yesterday.

This version is completely unusable. Reverting to previous version and it works as normal. Thanks for the quick temp fix @nadar

mntolia commented 4 months ago

Same here on my Ubuntu 22.04. Everything is super slow. I temporarily fixed it by disabling GPU acceleration: code --disable-gpu

briskycat commented 4 months ago

Not only is version 1.90.1 very slow, but it also crashed on me when I scrolled through the release notes (which were also very laggy). I'm on Ubuntu 22.04 as well, running VS Code from snap. Rolling back to the 159 release fixes the sluggishness.

same issue

reverting to 1.90.0 helps

filippocastelli commented 4 months ago

confirmed issue on two different machines (ubuntu 23.10 and ubuntu 24.04) running snap code 1.90.1 611f9bfc release

100% cpu usage by simple text scrolling on both machines, no extensions enabled Solved by uninstalling the snap version and reinstalling the .deb release.

Stuff like this - completely breaking usability on a whole release line - should not be passing QA

Snap revert:

sudo snap revert code --revision 159

error: cannot revert "code": cannot find revision 159 for snap "code"

To switch to revision 159/v1.89.1 if it is not in your snap revision history anymore, (error: cannot revert "code": cannot find revision 159 for snap "code"), you can remove and reinstall VSCode with:

sudo snap remove code

And reinstall revision 159 with:

sudo snap install code --revision 159 --classic

Note: This will keep revision 159 only until the next release is published and will not remove user data, i. e. opened workspace, extensions etc.
