As you're no doubt aware, using a PPA is at the moment the only way to use GNOME 40 without compiling it from scratch or switching to another distro. However the PPA does not ship GTK3, only GTK4 - hence this is a bug in an Ubuntu package.
Since this bug occurs in Ubuntu's packaged version of GTK3, and has already been fixed upstream in an API & ABI compatible branch, surely it is reasonable to request the fix be packaged here? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1922464 Title: GNOME 40: GTK3 apps crash with: Settings schema 'org.gnome.settings- daemon.plugins.xsettings' does not contain a key named 'antialiasing' Status in gtk+3.0 package in Ubuntu: Incomplete Bug description: Applications running with GTK < 3.24.26 crash when running under GNOME 40. This was fixed in GTK 3.24.26 by MR https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/3219 Please package either current GTK 3 (3.24.28) or include the given MR in the current build. Thanks!
