Decided to try writing a Wayland compositor for fun. Took me a few days to get things going to a video-able state.

Fixed transparency support. Turns out the BGRA format should've been in a separate pod, rather than as a choice in the same pod. Should've looked at Mutter code sooner as usual..

Apparently there's a cool Pango flag that enables subpixel glyph positioning which makes things scale smoother and improves kerning! Thanks Benjamin (the GTK maintainer) for the suggestion

Oops, looks like niri had outstarred PaperWM on GitHub
PaperWM introduced me to (and made me fall in love with) scrollable tiling. It's a solid implementation on top of GNOME, so you get all the benefits of running a stable and well-supported DE (and Xwayland). PaperWM is also a very direct inspiration for many parts of niri!

Implemented the thing where you can toggle the mouse pointer on the screenshot after the fact (by pressing P). Gonna add a help panel here soon to remind you of this.

One of the niri users has contributed a gradient interpolation color space setting! Now you can do pretty gradient borders in srgb-linear, oklab and oklch (in all four hue directions).

I made a COPR for git builds of niri: https://copr.fedorainfracloud.org/coprs/yalter/niri-git
Apparently this is a thing you can do; relatively easily, even. It's fully automatic, triggers on a webhook from GitHub.
Thanks Michael (my4ng) from our Matrix channel for showing me the relevant docs and doing the initial work!

also in an act of severe procrastination i decided to try drawing a diagram of the redraw state machine: https://github.com/YaLTeR/niri/wiki/Redraw-Loop

Spent a better part of today, but I've got dmabuf modifier negotiation fully working in my pipewire screencasting code in niri! This happens to finally fix screencasting on NVIDIA GPUs. Still haven't got any GStreamer pipeline working though, maybe needs a pipewire update.
Apparently, my AMD selects a BGRA format modifier that has two planes. Some out of band info I suppose. And on Intel a preferred BGRA modifier has three entire planes!

Several days and a lot of hair pulling later, I *think* I got resize transactions working?? Maybe? Hopefully?
Resize transactions is when all windows that must resize together, resize together, with no mismatching frames in between. For example, all windows in a column must add up to the full screen height.
This requires correct configure acks on the client (looking at you, Blender) and very careful state update delaying and resize throttling on the compositor side.

narrator: there was still one case where it didn't work due to a bug
okay, surely this time it definitely works for all correctly written clients

Here's one mainly for people who disable animations: window closing now runs in a transaction with the other windows resizing. This means, no background flicker.

There's been another logo discussion in the niri Matrix room with some quite interesting concepts emerging. Here's one by Endg4me_ with edits by bluelinden and myself, and inspiration from a concept by ElKowar.
What do you think?

I'm working on an "event stream" IPC for niri where you get notified about events as they happen. For example, "workspace switched" or "keyboard layout changed".
To give it a good test, I actually started implementing native niri support in Waybar. You can give it a try too: https://github.com/YaLTeR/niri/pull/453#issuecomment-2317110904

I finished the initial event stream IPC implementation for niri. My Waybar fork implements a decent amount of the modules niri/workspaces, niri/window, niri/language. Please give that a try, also anyone who makes IPC scripts or bars please give a try to the event stream IPC itself so we can find any design flaws before merging.
The PR you will need: https://github.com/YaLTeR/niri/pull/453#issuecomment-2321730996
Waybar fork is linked from there.
