[Frame Transparency Transient State] Frame transparency updates delayed until application loses and regains focus #17079
Description
Description 
The Frame Transparency Transient State no longer responds immediately. I need to switch from one Emacs to another application to make changes take effect.
Reproduction guide 🪲
- Start Emacs
- SPC T T (enable transparency)
- Alt+Tab (switch to the last application)
- Alt+Tab (switch back to Emacs)
- SPC T T (disable transparency)
- Alt+Tab (switch to the last application)
- Alt+Tab (switch back to Emacs)
Observed behaviour: 👀 💔
- Frame transparency isn't effective until I switch back and forth between
applications. - While reporting the issue I used Helm M-x to
sort-lines, and that also
triggered frame transparency updates, but not reproducibly.
Expected behaviour: ❤️ 😄
Frame transparency changes take effect immediately.
