I verified that this regression also shows in Fedora 37. I verified there because Fedora and Ubuntu ship a patch to enable transparency in gnome-terminal; gnome-terminal upstream does not have that feature.
I also verified that this regression was introduced in mutter 43.1. (transparency works in 43.0 but not in 43.1). With that information, I found an upstream bug report. The initial response was that the new behavior conforms to the specification and it was suggested to maximize gnome-terminal instead of using fullscreen mode if you want this feature. ** Changed in: mutter (Ubuntu) Assignee: Jeremy Bicha (jbicha) => (unassigned) ** Bug watch added: gitlab.gnome.org/GNOME/mutter/-/issues #2520 https://gitlab.gnome.org/GNOME/mutter/-/issues/2520 ** Also affects: mutter via https://gitlab.gnome.org/GNOME/mutter/-/issues/2520 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2003104 Title: gnome-terminal transparency ignored in full screen mode To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2003104/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
