In clutter_text_queue_redraw_or_relayout() we check whether the size of the layout has changed and queue a relayout if it did, otherwise we only queue a redraw and save some resources. The current check for this also queues a redraw if the actor has no valid allocation. That seems right on the first glance since the actor will be allocated anyway, but we actually want to call clutter_actor_queue_relayout() again here because that also invalidates the size cache of the actor which might have been updated and marked valid in the meantime. So make sure the size cache is always properly invalidated after the size of the layout changed and also call clutter_actor_queue_relayout() in case the actor has no allocation. This fixes a bug where getting the preferred width of a non-allocated ClutterText, then changing the string of the ClutterText, and then getting the preferred width again would return the old cached width (the width before we changed the string). The only place where this bug is currently happening is in the overview, where we call get_preferred_width() on the unallocated ClutterText of the window clone title: When the window title changes while the ClutterText is unallocated the size of the title is going to be wrong and the text might end up ellipsized or too large. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1150 |

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 af 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.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
