High CPU Usage Over %300

[ignacioxyz]

Type: Bug

I just installed VSCode on a brand new laptop. I have not installed any extensions or opened any code projects yet. While I was installing other tools that I need, I noticed the laptop became laggy. This was caused by VSCode using over 300% of the CPU.

VS Code version: Code 1.91.0 (Universal) (ea1445cc7016315d0f5728f8e8b12a45dc0a7286, 2024-07-01T18:54:18.541Z) OS version: Darwin arm64 23.5.0 Modes:

Same issue on Fedora. vscode is extremely laggy, input delay is over a second, completely unuseable. I tried without extensions too, same issue. It works as expected a few seconds after opening any project, but then the lag kicks in and vscode occupies around 30-80% of CPU usage as reported by htop.

Seems to also be that vscode is capping framerate at 60 and dropping frames all over the place, even on an 120hz monitor
