Merged another long time overdue niri PR: mouse cursor via metadata in PipeWire screencasts (lets you toggle Show Cursor on/off in OBS), and full mouse cursor support in window casts.

The cursor is visible only when the window is receiving mouse events—if you're moving the mouse on top of something else covering the target window, the cursor won't be (unintentionally) painted.

Thanks @abmantis@mastodon.online for driving this, including debugging a memory bug in PW!

Working on a screencast IPC for niri. The idea is to give info to desktop bars to be able to add a screencast indicator whenever something is recording the screen.

Got it hooked up for both PipeWire (obviously) and wlr-screencopy. For the latter there's no good way to tell if something is a screencast so I went with some heuristics.

Here's the icon working on the DMS bar, as well as a popup with the full available info I made for debugging. blobcat

Oh right, for PipeWire I can send the node ID, which DMS can then use to fetch the consumer application name!

Also added niri msg action stop-cast to force-stop a PipeWire screencast

So yeah, I'm working on blur for niri. I'm doing "xray blur" first where the idea is that you only include background surfaces, so you pretty much never have to redo the blur—next to zero perf impact unless you have a video wallpaper or smth.

Turns out that it's quite tricky to do well, especially with our Overview. I'm like on my third refactor attempt now but I think I've got a good approach.

During this video there's no reblurring whatsoever, all just drawing cached static textures.

Added non-xray blur, based on @drakulix@social.dreampi.es's Smithay/COSMIC implementation.

Keep in mind this blur work is still extremely WIP and with many issues (some visible on the video). It's also still not entirely clear to me how to best structure the code around it in niri. We'll see
