Random file save failures

[rob99]

Issue Type: Bug

Behaviour

When editing a ipynb file, seeing some erratic behaviour. Often when saving file, tab icon turns from dot to X (indicating file has saved) yet the file has not saved. Sometimes screen flickers and changes are lost (previously saved file is reloaded). Or else closing and reopening the file I can see that changes have not been saved. Also can confirm file is not saving by monitoring ipynb file from Notepad++

Other oddness: Running a cell, sometimes the timer disappears, or cell output disappears, and it looks like the cell has finished running (but it has not).

I have completely uninstalled and reinstalled VS Code and extensions. Also manually deleted %appdata%/Roaming/Code and %home%/.vscode.

Expected

File to save

Actual

File not saving (on random occasions). Old file is reloaded, changes are lost.

Steps to reproduce:

1. Not known.

[rebornix]

@rob99 can you please update to the latest Stable and see if you can still reproduce?

[rob99]

@rebornix I have updated to the August release and the problem has not reoccurred.

[rob99]

I have now updated to v1.61 and the problem is back

[rebornix]

File not saving (on random occasions). Old file is reloaded, changes are lost.

From what you described above, it's probably the same as #135516

[julie777]

I am not sure if my problem is the same.

I frequently use ctrl-k, s to save all files and sometimes not all of them are saved.

[rebornix]

It would be great if anyone of you open Developer Tools and share the logs there if you run into this again.
