The marco WM is used in Arctica Greeter [1]. There recently has a security issue been detected where people could open applications via marco keybindings inside the greeter (display manager) session. . A work-around could be evoking marco-message after marco startup and disable all keybindings then. However, a more preferred fix is provided by this patch: start-up marco with keybindings disabled from the beginning.
A prior commit switched from focusing the topmost window as the default window to focusing the MRU window. This was done in alignment with the introduction of per-workspace MRU lists to avoid problems where the window stack was inadvertently changed when focusing windows during window switches. Now that focusing windows don't have as big an impact on the stacking order, we can revert back to focusing the top window, which is less confusing to the user. For now, leave per-workspace MRU lists, as they're a pretty good approximation of a global MRU list, and it works well enough. https://bugzilla.gnome.org/show_bug.cgi?id=620744 Based on commit https://gitlab.gnome.org/GNOME/metacity/-/commit/f628d8f8901f46fa9e00707ae9d7ccfd1e85f427
Shadow and padding was never part of theme. This format was created by mutter, and it is an incompatible change.
Add an additional color type to pick up colors defined with @define-color in the GTK+ theme's CSS: gtk:custom(name,fallback) (where "name" refers to the name defined in GTK+'s CSS, and fallback refers to an alternative color spec which is used when the color referenced by "name" is not found) The main intent of the change is to allow designers to improve Adwaita's dark theme variant without having to compromise on colors which work in the light variant as well. https://bugzilla.gnome.org/show_bug.cgi?id=648709 NOTE: Patch copied from mutter and adapted for metacity.
It may be desirable for theme authors to treat side-by-side tiled windows differently, for instance to give the edge-touching border a width of 0, so add additional frame states for tiled windows. https://bugzilla.gnome.org/show_bug.cgi?id=637330 NOTE: Patch copied from mutter and adapted for metacity. This adds only description in doc/theme-format.txt as all other changes has been added already.
With the existing background functions, single buttons can not be styled separately - on the left side, the style of the left button is picked, and the right button's style on the right side. As theme authors may want to add rounded corners to button groups as a whole, it makes sense to treat the case of a single button in a group differently. https://bugzilla.gnome.org/show_bug.cgi?id=635683 NOTE: Patch copied from mutter and adapted for metacity.
