Vscode: VS Code freezes

[MartinAskestad]

Issue Type: Bug

When I use VS Code it will suddenly freeze, completly unresponsive to keyboard or mouse, if I put the Code in the background by switching to a web browser or e-mail client or anything, it seems to run and what I typed on the keyboard suddenly appears. It seems that Code is listening to the keyboard and mouse, but can't display back what is going on until I put the app in the background. Sometimes the entire window will go black after a few seconds the contents are drawn again except for the code-minimap and integrated terminal. These stay black, usually until I reload the window or restart Code.

I've had these problems before, but they went away until a couple of days ago when code updated to 1.28, and now it's back with a vengance making it almost impossible to use.

This is the output from code --status, hopefully during a freeze, since it doesn't freeze when Code isn't in focus it's a bit tricky to start the --status thingy.

Can you please report a Performance issue when this happens. A performance issue (Help>Report Issue>Performance Issue) it includes more performance related information and it is readable.

Please try to narrow it down whether it is an extension and which extension it is by following this guide https://github.com/Microsoft/vscode/wiki/Performance-Issues.

[MartinAskestad]

This is the output from the report performance issue dialog. I did also try to start Code with the --disable-gpu flag and it seems to help. Code doesn't freeze when I run with disabled gpu.

Issue Type: Performance Issue

[MartinAskestad]

I can almost guarantee that the problem is related to gpu acceleration. I've been using code with --disable-gpu for about a week now and there has not been any problems.

[bpasero]

We are building exploration builds that use a much newer version of Electron (our UI framework). I wonder if this issue reproduces with one of these builds, could you try? Download:

• macOS: Download
• Linux: Download
• Windows: Download

[MartinAskestad]

@bpasero I've used the exploration version all friday and a bit this morning and it seems to run just fine on my computer. Haven't experienced any problems.

[graph]

Here is some info. Sometimes it happens way too often, sometimes it doesn't happen much. @bpasero are you able to share the schedule or timeline for exploration going to stable?

I also started to experience freezes after upgrading to VS Code 1.29.0 yesterday.
It never happened before.

Also experiencing this issue. VS Code would become irresponsive after moderate use and I have to either wait for it or kill the application.
VS Code: 1.29
OS: macOS High Sierra 10.13.3 (17D47)

[Pavel-Durov]

Same here.
VS Code would become irresponsive (I've removed all installed extensions) when trying to close the application I am prompted with:

Version 1.29.0 (1.29.0)
5f24c93878bd4bc645a4a17c620e2487b11005f9
OS: mac OS Majave 10.14.1

[dokicoder]

I second this. It happens at least every half hour. Seems to become more frequent when multiple tabs are open.

[Pavel-Durov]

It seems that it's more of an environment configuration issue.
Same VS Code version on 2 different machines (with the same OS version) works differently - one freezes every 30 minutes, while the second one works fluently.

[aacotroneo]

same issue - update to 1.29.1 seems to have fixed it - at least for the moment. For me the freezes didn't start immediately after installing 1.29.0, so probably something related to the installation files/config/state. May be the update itself cleaned something up (don't see any direct fix in the changelog)

I will note that I upgraded to version 1.29.1, and I have small intermittent freezes everytime I save a python file and the linter runs on it. I switched to the exploratory version which has Electron 3.0.1 and it runs fine.

Running v1.30.0 on Ubuntu 16.04 with any NVIDIA driver leads to long start ups / freeze on startup. After about 5 - 10min I can use code as usual. When I start code with --disable-gpu everything is fine.

I've experienced this problem since upgrading to 1.30.2. It occurs whenever changing focus from emulator to code or whilst autosaving/hot reload.
I've downgraded to 1.29 and the issue is gone.

We are building exploration builds that use a much newer version of Electron (our UI framework). I wonder if this issue reproduces with one of these builds, could you try? Download:

• macOS: Download
• Linux: Download
• Windows: Download

No problems using the experimental 1.28 on macos 10.14, and when using default vscode 1.30.2, freezes continue

both visual code and the experimental above freeze _very_ frequently (for about 10-30 sec each time) .. this is very poor experience ..

Using windows 10 latest updates
--disable-gpu does not help
when the editor unfreezes whatever keys were entered during the freeze are 'played'

it feels like some background task is freezing the editor

Just a guess - yesterday my internet connection was really bad and today it is sorted and VS Code is fine ... perhaps there's some waiting for upload/download in the bg ...

I'm doubtful that is the case for me as at work we have a 100mbps up and 100 mbps download speeds, the issue only started after upgrading VSC and ceased when it was downgraded.

Reading some of the descriptions others have given I think it might related to project size or number of tabs.

[bpasero]

Closing this issue given that we plan to release VSCode stable early February with Electron 3.x. If you want to benefit from the fix already, consider to use our insiders version that already contains the fix: https://code.visualstudio.com/insiders/

[kofifus]

This still happens to me very frequently on vscode insiders
Can this issue be reopened ? otherwise should I open a new issue ? where ?

[danipoak]

Ditto. VS Code has become unusable with the constant freezing. Tried with the --disable-gpu option but no luck. Only one tab open as well.
