alt Hacker NewsEmacs user for >32 years now. It's a pity this won't get merged. There is a big usability/accessibility factor to consider here: I really wish I could have something like the Ghostty cursor_blaze.glsl shader for highlighting where the cursor is when you switch windows/buffers/apps.
Most people think GPU equals silly toys like video in a text window, but there is much more to it than that.
[and yes, I know about beacon, which unfortunately doesn't work too well, as well as about pulse, which I use]

I would love to have something like nvim's "smear-cursor". iirc someone wrote a patch (it was posted on r/emacs) - I'll attach it if I find it. My first thought was "is it doable as a dylib?"
I'd be thrilled with a second thread much less GPU.
I don't think video in a text window is a silly toy. Sounds like another useful tool in the toolbox.
GPU speedups are welcome, but you don't need a shader and a gpu to insert a flashy effect.
Emacs has had this for decades: `pulse.el`. And building your own is very simple also.
You'll still need someone to write the glue code to trigger the pulse, but then a gpu patch on the backend wouldn't give you that either.
I'm sure someone on MELPA/Github has written code to do just this already.
