For completeness I bisected the cause of the issue (introduced in mutter 43.1):
909616b20876478bc56932cd18c8e85e982645f6 is the first bad commit commit 909616b20876478bc56932cd18c8e85e982645f6 Author: Sebastian Wick <sebastian.w...@redhat.com> Date: Tue May 3 18:47:57 2022 +0200 window-actor/wayland: Draw black background for fullscreen windows Fullscreen Wayland toplevel surfaces don't need to respect the configured size in which case it should be shown centered on the monitor with a black background. The black background becomes part of the window geometry. The surface container is responsible for correctly culling the surfaces and making sure the surface actors are removed from the actor tree to avoid destroying them. The window actor culling implementation assumes all surfaces to be direct children of said actor. The introduction of the surface_container actor broke that assumption. This implements the culling interface in MetaWindowActorWayland which is aware of the actor surface_container and fullscreen state. v2: Fix forwarding culling to surface even if there is a background. v2: Don't alter passed geometry. v2: Update window geometry code documentation to reflect these changes. v2: Only use constrained rect if we're acked fullscreen.

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.
