[Bug]: macOS: Constant 30%+ CPU usage by Feishin Helper (Renderer) process in 1.8.0

[nano9g]

I have already checked through the existing bug reports and found no duplicates

• Yes

App Version

1.8.0

Music Server and Version

Navidrome 0.60.3

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 Sequoia 15.7.4 arm64

Please let me know if any additional information including logs, process samples, etc. would be helpful.

Steps to reproduce

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

I just tested old versions and this issue does not occur prior to 1.8.0; CPU usage is normal in 1.7.0 and prior.

Can you make sure that you did not download the wrong arch?

For example, if you are on arm64 that you did not download x64 and vice versa.

Thanks for the suggestion! I just re-downloaded 1.8.0 arm64 to be absolutely sure, and unfortunately it's still exhibiting the same behavior.

That's strange.. nothing was changed regarding the macOS build between 1.7.0 and 1.8.0 except an upgrade to the electron-builder package.

Let me set up a v1.8.0 build using the previous electron builder version so I can have you test.

Download the macos-binaries under the Artifacts of the build and check if it exhibits the same high CPU issue.

That build also has the CPU usage issue. 🙁

As a "what if", I backed up and reset my Feishin preferences, and that didn't change anything either.

I'm happy to do any other troubleshooting that might be helpful.

Not sure whether this is the same problem, but on Windows, Feishin also causes constant CPU load even when minimized and doing nothing in background. For me, this also started with the recent update and old versions never had this issue.

@IceStormNG Hmm.. might not be a macOS specific issue then. I just checked myself on Windows and I'm seeing 2.8 - 4% CPU on idle.

I'll do some debugging to see which commit caused it.

I'm seeing 2.8 - 4% CPU on idle.

That's also about what I am seeing on my system. The older releases where between 0% and 0.1% in background.

After running a git bisect, I have found the culprit!.

I re-enabled the skeleton loading animations in the last release but apparently they're not optimized. as they are causing high CPU usage even when not visible.

Will push a fix soon.
