What local environments are you seeing the problem on?

Desktop macOS

What happened?

Whenever Feishin is running, the Feishin Helper (Renderer) process uses 30-35% CPU. This occurs:

Regardless of whether music is playing.
When it's just sitting idle and nothing appears to be actively happening in the UI (navigating to different sections of the app doesn't make any difference).
Even if the Feishin window is hidden.

Environment: macOS Tahoe 26.6.2 arm64

Found a previous issue for this which said it had been resolved but unfortunately not.

Steps to reproduce

1. Open Feishin on arm64 macOS.
2. Check Activity Monitor and observe high CPU usage.
