VSCode randomly semi-freezes #112269

Closed MMK21Hub closed 3 years ago

MMK21Hub commented 3 years ago

Issue Type: Bug

  1. Use VSCode for a while
  2. Eventually it will go into a state when you can't type

Sorry that this isn't reliable to reproduce. I have not had this problem with another app that uses the Monaco Editor.

Nothing suspecting from above info.

Please profile your renderer using this link - https://github.com/microsoft/vscode/wiki/Performance-Issues#profiling-the-renderer-process and share us the profile.

Indy9000 commented 3 years ago

sporadically freezes while typing or scrolling and unfreezes after a second or so. Happens very frequently this makes VSCode pretty unusable.

Here's the VSCODE info

Managed to get a profile.

sandy081 commented 3 years ago

I do not see any suspicious things in the profile

@MMK21Hub It could be also due to an extension - have you checked that?

@jrieken Do you have any other suggestions for the user to follow to know about the perf issue?

jrieken commented 3 years ago

Profiling is the best but sometimes it is tricky to capture the actual slowness when profiling. I can only recommend to keep trying

ucirello commented 3 years ago

I tried running VSCode in safe mode (code --disable-extensions) and the behavior is the same as when the extensions are enabled. As it is, I can use it for read operations only. Actual interactive operation is not usable anymore.

I attached the JS profile as per in https://github.com/microsoft/vscode/wiki/Performance-Issues#profiling-the-renderer-process

Thanks. I see that spawning at +1.5sec which isn't good. This can happen on macOS BigSur and windows. Passing it to @deepak1556

ucirello commented 3 years ago

Well - the freeze happens after the shell has spawned. So there may be two instead of one problem.

lukel97 commented 3 years ago

Chiming in here to say I'm also getting pauses on big sur with extensions disabled, with a similar looking profiler trace as @jrieken Code 1.52.1 (ea3859d4ba2f3e577a159bc91e3074c5d85c0523, 2020-12-16T16:30:02.420Z)

@ucirello @bubba @Indy9000 the issue you are facing is tracked at https://github.com/microsoft/vscode/issues/105446 , please follow that for updates. Thanks!

You can check https://github.com/electron/electron/pull/27026 and the corresponding libuv issue for more details on the root issue.

deepak1556 commented 3 years ago

@MMK21Hub do you continue to see the issue with latest insiders 1.53

MMK21Hub commented 3 years ago

I have just experienced the issue again. image

deepak1556 commented 3 years ago

@MMK21Hub can you open a new issue with the --status and cpu profile results. Thanks!
