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 Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2003104 Title: gnome-terminal transparency ignored in full screen mode Status in Mutter: Unknown Status in mutter package in Ubuntu: Triaged Bug description: Ubuntu 23.04 running wayland gnome-terminal 3.46.7-1ubuntu1 In gnome-terminal, I have set the transparency to some amount. When I go to full screen (F11), the transparency is lost and the default transparency is used. When I exit full screen, the transparency comes back and I can see in the profile settings that the transparency has not changed. It seems that tranparency was accidentally removed, and then re-added via https://git.launchpad.net/ubuntu/+source/gnome-terminal/tree/debian/patches/0001-Restore-transparency.patch?h=applied/ubuntu/lunar-devel However, maybe something was missed with regards to full screen.
