Public bug reported: [ Impact ]
4.18.5 is a new bugfix release from upstream: https://gitlab.gnome.org/GNOME/gtk/-/blob/4.18.5/NEWS?ref_type=tags * Bugs fixed: - #5844 `gdk_surface_get_device_position: assertion 'GDK_IS_SURFACE (surface)' failed` on popover close (Alessandro Astone) - #7451 Cairo device scale changes lead to significant performance regression in cairo blur (Sebastian Keller) (bug 2107245) - #7479 gtkmm programs fail to start on Windows with AccessKit support enabled (Matthias Clasen) - #7482 Epiphany Crash in GTK file chooser when last used directory has insufficient filesystem permissions: "GFileInfo created without standard::type" (Philip Withnall) - #7495 Failed to link with the mold linker (Matthias Clasen) - #7513 Broken boxed-list ListBox (Sergey Bugaev) - #7520 XCompose preventing GTK4 applications from launching (again) (Matthias Clasen) - #7522 critical when selecting label with use-underline but mnemonic with screenreader enabled (Markus Göllnitz) [ Test Plan ] Test Case 0 ----------- gtk4 has an extensive build test suite, and failures will fail the build. gtk4 also has thorough autopkgtests. Ensure that the build succeeds and that the autopgktests pass. Test Case 1 ----------- Make sure that opening and saving files from the Firefox and Chromium snaps still work Test Case 2 ----------- snap install portal-test --edge snap run portal-test Verify that the app seems to still work ok Test Case 3 ----------- Install and test gtk4-demo (from the gtk-4-examples package) as well as a few other GTK/GNOME applications like nautilus and gnome-text-editor, and verify that they continue to launch and work as expected. [ What Could Go Wrong ] Many of the default Ubuntu desktop apps use GTK4. A serious enough regression could severely break the Ubuntu Desktop. Ubuntu includes xdg-desktop-portal-gnome by default which is used for many snap actions like providing a file chooser. This is critical functionality for our snaps. The Ubuntu flavors use a different portal backend, most commonly xdg-desktop-portal-gtk which uses GTK3, so are not affected by this SRU.
