High CPU usage due to spinner animation in VSCode status bar

[andreialecu]

Type: Performance Issue

When the Github Copilot extension is installed in VSCode, the spinner animation in the status bar may get stuck and cause high CPU usage for the "Code - Insiders Helper (GPU)" process, even when the editor is idle.

I have attached a video demonstrating the behavior.

This seems to occur for both Github Copilot or other extensions that may produce a spinner. See phenomnomnominal/betterer#1132 for a related issue.

Same issue with me

[deepak1556]

Is the issue present with latest insiders ?

[andreialecu]

@deepak1556 I believe so, it's harder to get it to spin consistently though. I believe a previous version of the extension had a bug and it would get stuck sometimes.

However, if I make it do some work and get it to think for a while, I can see the same GPU process shooting up in usage and staying there for as long as the spinner is active.

I didn't have the absolute latest Insiders, it seems; there were some pending updates. Did you mean an insider from today?

[andreialecu]

I believe this is still present, see recording from today:
