Ivan Molodetskikhi'm reviving the PR integrating Tracy GPU profiling into Smithay. Here are two test captures from niri: one for normal + screencast rendering, one for iGPU + dGPU monitor rendering
#niri
Ivan MolodetskikhLooking for ideas on how to go about translating niri (the binary, and the wiki). If you have experience doing this with other FOSS projects, please share:

Ivan MolodetskikhIs there any good way of moving a process into a systemd StartTransientScope together with its children?
In niri we put spawned processes into scopes, so oomd and other stuff can work properly. Usually you do it by putting yourself into a scope, then exec-ing the target program. But that's a 7 ms toll on startup time, so in niri we spawn the program right away, and then put it into a scope. However, if the program forks fast enough, that child doesn't go into the scope..
#niri #linux #systemd
Ivan MolodetskikhTurns out GNOME Shell has the same problem: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6565
I also wrote it down in a more detailed form on the niri issues for future reference: https://github.com/YaLTeR/niri/issues/3201
Ivan Molodetskikhniri can now include the mouse pointer on window screenshots, a feature that had several more edge cases than I thought before starting to work on it (and it's likely not the ones you think, those ones were easy)
#niri
Ivan MolodetskikhMerged 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!

Ivan MolodetskikhWorking 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. 
#niri
Ivan MolodetskikhOh right, for PipeWire I can send the node ID, which DMS can then use to fetch the consumer application name!
#niri
Ivan MolodetskikhThe screencast IPC is now merged: https://yalter.github.io/niri/niri_ipc/struct.Cast.html
#niri
Ivan MolodetskikhAlso added niri msg action stop-cast to force-stop a PipeWire screencast

Ivan Molodetskikhworking on my new visual style
#niri
Ivan MolodetskikhSo 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.
#niri
Ivan MolodetskikhAdded 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
