This disables the visibility change effects for the dragged window, which makes it feel a bit smoother. TODO: Double-check whether this is indeed desirable. Note: ChromeOS imp does this and Chromium-X11 used to do this at client side. Status: - [x] Basic window drag triggering - [x] Exclude the dragged window from event targets - [x] Event forwarding (window drag vs wayland grabs) - [x] Offset calc relative to toplevel geometry - [x] Attach already mapped windows - [x] Properly support not-yet-mapped windows - [x] Disable visibility change animations - [ ] Dnd events stream adaptations Signed-off-by: Nick Diego Yamane <nickdiego@igalia.com> Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4107>
Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
