Okay. Finally found the reproducer: it's the visual bell during screensaver.
Attaching a screenshot. Reproducing: - Settings -> Accessibility -> Hearing -> Visual Alerts -> On (Flash the entire Window) - Open a gnome-terminal - type: xdg-screensaver activate; printf '\a' - Wake up the screensaver, and notice that the window in which there was a bell, is darker. Note that changing the Visual Alert to "Flash the entire screen" fixes the issue. It tried this just now on a different Ubuntu/Jammy, and the results are the same; 100% reproducible. ** Attachment added: "Screenshot from 2024-06-15 21-47-11.png" https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/2064716/+attachment/5789927/+files/Screenshot%20from%202024-06-15%2021-47-11.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064716 Title: gnome-terminal sometimes very dark after gnome unlock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/2064716/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
