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.

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

Managed to get a profile.

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?

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

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

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

Chiming in here to say I'm also getting pauses on big sur with extensions disabled, with a similar looking profiler trace as @jrieken
