Hello?
Today, I briefly read the source of the emacs.
It's a small amount of time, so it may not be accurate..

What do you think about the coexistence of emacs-ng's webrender + emacs:feature/pgtk || webrender + emacs-mac?
Their processing methods are different and seem to overlap quite a lot.

I just want to ask how likely are they.
From my point of view, it is mutually beta now, and even if possible, there will be a lot of work.

I'm curious about your opinion because you have experience in integrating webrender.

What do you think about the coexistence of emacs-ng's webrender + emacs:feature/pgtk || webrender + emacs-mac?

AFAIK, webrender and pgtk can coexists in one repo because they all use the window system mechanism. emacs has a good support in multiple window system backends.

I'm not familiar with emacs-mac, so I can't tell anything about it before I dig into their code.

BTW, I used some code of feature/pgtk as references while implementing webrender's counterpart functions. 😄

Good news!!
It would be great if Linux supports webrender + pgtk.

--with-mac-metal in emacs-mac seems to be able to collide.

Firstly, thanks for the great project! It struggles to build on my m1 machine, but I reckon thats due to upstream issues out of your control. On my older laptop it runs much better than emacs-28!

Just some clarification on emacs-mac and the benefits/drawbacks (as well as those discussed here: #99)

The biggest improvement is the application-side double buffering with metal

Emacs Mac actually disables this option by default, since it doesn't offer any improvement over openGL. The double-buffering works under openGL as well, so you can remove metal if it collides.

Touchpad gesture support (can't verify), Better clipboard/dnd support (?), Better support for the right ⌘ and ⌥ keys (?)

Although there is better touchpad gesture support, the clipboard and cmd/alt keys are about the same for stock and emacs-mac.

Personally, I believe that it isn't worth switching to emacs-mac, and having a significantly different codebase for both linux and macOS will just lead to parity issues down the line, as well as more bugs. I believe Emacs-plus (the base code itself is here, thats just the install formula) would be a better choice to work off of. It fixes most of the bugs you mention (including the double buffering issue).

How about use emacs-ng in wsl2 experience
