Opacity blur setting not working in macOS

[ciscohack]

Hi,

First thanks for this plugin. Opacity blur level hardly show any effect on my macOS 12.0.1. I have tried all values from 0 to 1 and nothing blur the background. only setting working fine is Opacity

I also met this problem. The opacity works but blur doesn't work.

My system is macOS 13.1 ventura with Apple M2 chip CPU.

Any solutions? Thanks!
