GNOME Mutter 3.25.92 Adds Built-In Screencast / Remote Desktop Capabilities

[Tomin]

Curious.

I saw there's a Redshift implementation based on top of GnomeRR/Gnome Desktop Library.
Can that one be used outside of Gnome3 or does the Gnome-Desktop library depend on the rest of the Gnome stack?

I'm not sure what you are talking about, but currently with latest Gnome there is Night Light option in display settings which does what Redshift used to do and it works on both X11 and Wayland. I think it works fine (I use it), but you might want to tweak the color temperature to suit you better, which unfortunately must be done using dconf (dconf-editor). Previously the Wayland solution was to use patched Gnome control center together with Redshift Gnome extension. Also this tapped the same color settings that Night Light currently does. I don't know how portable this code is, so I can't comment whether it will be usable on other compositors as well, but my guess is that it probably is worth to take a look at when implementing this on some other compositor.

I think on Windows the UX rules are minimized window comes back to where it was while a (closed and) newly started window comes up at in the middle of the screen. Does Gnome behave different? (oh, right, they don't have minimizing windows so they need a different UX)

Actually, on Windows windows (heh!) come up exactly where you last closed them. It even conserves the display (when running on a multi-display setup).
Wayland doesn't even have a concept of absolute window positions, so things behave quite differently over there.

It seems Mutter have worse window positioning on Wayland than on X11.

On X11 I get sane window positioning. Applications usually open in the same place as I closed em.
On Wayland the window positioning is weird and often opens at some predefined position.

On X11 I can do WinKey+Left/Right and the window moves with a smooth animation.
On Wayland the window just jumps without any animation.

Afaik the Linux implementation of miracast is here.

Requires a frontend, but nothing that can't be done with a shell script + zenity GTK for the graphical user interface.

Yeah I've tried that, at various points. I had it able to connect and send some frames before crashing, with a previous laptop / wireless card. It doesn't work at all using my current laptop. Also, the requirement that you kill wpa_supplicant and networkmanager doesn't really fit in with the typical use-case where you'd need both of these to connect to corporate wireless. Apparently a guy @ Intel had something working, but wants to completely re-implement and relicense as BSD before making a public release. This was years ago, mind you. Luckily everything I want to display on still has an HDMI port ...

On Xorg applications can move their own windows around where on Wayland only the compositor can. Ideally GNOME starts saving the position I find it annoying too.

The animation thing is just a bug which I believe is known (haven't tested 3.26).

Does anyone know something about builtin miracast mirror support like in win10? Would be useful

Typo:

the Mutter compositor has introduced scrensharing support itself.
