Here is a patch that adds this option as a frame parameter. I hope I did everything correctly, but I have never worked with the Emacs C source before, so I probably made some mistakes in style or logic. Also, should this be factored out so that `border-alpha-background' is its own parameter? In that case, a lot of functions would need to be changed (the `respect-alpha-background' parameter in many xterm.c functions would probably be changed to just a `double alpha` or something like that). I am up for that, but I'm not sure if it would be a helpful change. Please let me know how it looks! On Sat, Oct 12, 2024 at 8:38 PM Po Lu wrote: > > Eli Zaretskii writes: > > > Ping!
