[Bug] The FFT Spectrum's response time only applies to frequencies above 8 kHz

Here's a video showing the issue:

I've already tried restarting the application and choosing different FFT sizes and frequency ranges, but the problem persists, unfortunately.

Can anyone else reproduce this on their end?
