[Feature request]: Feature Request: Add support for Issue #605

[JoshTRN]

Feature request description

Hi! I’d like to request consideration for adding the functionality discussed in #605.

In that thread, @d12frosted noted not being aware of support.
However, I’ve confirmed that support does exist in downstream forks:

• Initial fork: jaaasonSun/homebrew-emacs-plus
• Secondary fork (where the work was done): aaratha/homebrew-emacs-plus

I installed the secondary fork locally and can confirm that the transparency + undecorated patches work as intended. It would be fantastic to see this upstreamed into the mainline formula.

References

Key commits implementing the functionality:

• jaaasonSun/homebrew-emacs-plus@f70413b – Adds blur and fixes alpha-background for Emacs 30
• aaratha/homebrew-emacs-plus@4d9cfd0 – Adjusts blur view (switches material, sets blending mode, enables effect)

These commits could serve as a helpful starting point if you decide to port the feature upstream.

Notes

I understand that feature development and maintenance take significant effort, and I don’t want to underestimate the work required. I’m not submitting a PR myself because I’m not very experienced with Ruby formulas or patch maintenance, and I wouldn’t want to risk breaking anything upstream. That said, the patches in the fork work cleanly on Emacs 30 and could provide a helpful starting point if you decide to incorporate them.

Thanks for considering — and apologies for not putting this in as a polished PR myself.
