ghostty main on nixos crashes

[wmertens]

I'm building from main and I just built a ghostty that doesn't work.

It would be great if there was a released branch that points to the latest released version, so I can point the flake to that and not have to manually change the version on every update.

FWIW, here's the error:

Gsk:ERROR:../gsk/gl/gskglcommandqueue.c:599:gsk_gl_command_queue_begin_draw: assertion failed: (height <= G_MAXUINT16)
Bail out! Gsk:ERROR:../gsk/gl/gskglcommandqueue.c:599:gsk_gl_command_queue_begin_draw: assertion failed: (height <= G_MAXUINT16)
Aborted (core dumped)

Actually, 1.0.1 creates a window and crashes 2 seconds after that. The last working build I have is version=1.0.2-5cb2fa6-nix

Hmm, this was my fault. I was making the ghostty flake follow my nixpkgs and it seems that right now nixpkgs breaks the build.

So if I leave the stable nixpkgs alone and have the unstable nixpkgs follow my nixpkgs it builds a working ghostty.

I'll now just accept that I'll have several nixpkgs versions active. It sadly uses quite a few MB in old packages.

Possibly related: #3311

(It looks like Ghostty built via Nix might not be properly using the system integration and is linking fontconfig statically, leading to very funny things happening at runtime.)
