This prevents race conditions with applications like mate-screenshot that need to grab input (e.g. for area selection). Fixes mate-desktop/mate-utils#37
Extend MetaFrameBorders to include shadow and resize borders to calculate invisible border size. Also added border caching to prevent recalculating borders on every frame operation. This is a backport of the following commits from Metacity: - https://gitlab.gnome.org/GNOME/metacity/-/commit/21e664af - https://gitlab.gnome.org/GNOME/metacity/-/commit/3c6e269b - https://gitlab.gnome.org/GNOME/metacity/-/commit/700e87ea
In systems with bamfdaemon running, windows get this property for finding the dekstop spec file of an application. This can be used to find the defined icon for any application window that reports this attribute and provider much better icon matching.
Looking up GDesktopAppInfo from the GTK Application ID we can get a much better match for the icon and load it at the appropriate scale. This results in matching icons to straneous windows and better looking icons overall.
Enabling code that is supposed to be used in compositing conditions is harmful if compositing is not actually available. Just checking the preference is not enough to make sure that compositing is available - the X server might be missing crucial extensions for compositing to work, which in turn correctly disables the internal compositor. The end result is graphical issues like black borders around windows in such situations. Make sure that compositing is both requested AND available to fix this bug.
In addition to existing properties use also new _GNOME_WM_STRUT_AREA property that allows creating struts between monitors. https://mail.gnome.org/archives/wm-spec-list/2018-December/msg00000.html https://gitlab.freedesktop.org/xdg/xdg-specs/merge_requests/22 origin commit: https://gitlab.gnome.org/GNOME/metacity/commit/922de13
This pull request prevents shadows being rendered for left and right side titled windows. This behaviour is consistent with maximised windows, which also do not render shadows. The rationale for this change is so that when two windows are titled along side each other, it prevents central shadows bleeding into the touching points of the windows. metacity-theme-x.xml has provision to style left/right titled windows. This patch makes it possible to to create window themes that present clean side-by-side tiled windows.
Some files do not report their application icons correctly in the window properties. This patch allows the marco UI to search for the corresponding .desktop file and render the icon in the desktop info on both the alt-tab popup and the window mini-icon.
