After opening the terminal in full screen mode, it closes and restarts, but with the wrong geometry.

The window state is not persisted correctly upon closing an application that is currently set to fullscreen. If a user opens the application, switches it to fullscreen mode, and then closes the application without exiting fullscreen, the next time they launch the application, the window will appear maximized (taking up the entire screen space), but it will be in the windowed state (with visible title bar and window controls), not the true fullscreen state. The expected behavior is for the application to reopen in the previous state before it was in fullscreen mode.

This is up to the application to handle, please report it to the relevant apps.
