Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.78.2

Steps to Reproduce:

1. Make changes to a few files in your project, introducing issues or errors that would be displayed in the "Problems" tab of Visual Studio Code.
2. Revert the changes made in Step 1 using Git or perform any other Git operation, such as stashing or adding the changes.

When files are reverted problems tab starts flickering which can be seen on the attached gif below.

Do you mean the number being reduced and finally disappearing?

[larisafe]

Yes, the number jumped a few times before disappeared. In our case, we have a file watcher responsible for handling numerous files within our system. Whenever a file undergoes a change, we consistently invoke the function VsCodeManager.updateDiagnosticCollection to update the problems tab accordingly. Unfortunately, the rapid and frequent changes have resulted in an irritating issue, resembling a flickering effect, when there is a really big number of files changed. This problem has persisted for the past month or so and it came with the new version of vs code, as it was not present prior to that. So I am guessing that probably the rendering of problems was somehow changed recently.

Interesting, can you please let us know the last version of VS Code it is working as expected? Can you also please share the gif?

[larisafe]

I think that the problem started when we upgrade vs code engine version from 1.52.0 to 1.74.0.
I am sending you another gif of how flickering looks like when VsCodeManager.updateDiagnosticCollection is called frequently, for a large amount of changed files. The problem is the same as on the gif above, but the above diagnostic collections were not updated so frequently so flickering may not be so visible.

I think that the problem started when we upgrade vs code engine version from 1.52.0 to 1.74.0.

Can I presume that you do not see this behaviour before 1.52.0 ?
