When the background is black I don't know where is the bar

Maybe a white transparent background for the progress bar should be fine

What version of cleanHUD are you using? This is how it looks in the latest version:

Maybe it's an issue with dark mode not being detected.
If you open terminal and type defaults read NSGlobalDomain AppleInterfaceStyle what do you get?

I don't know what I did but now is working fine after a macos reinstall
