I was able to trigger this behaviour doing one of the following: * Changing to a desktop with at least one window on it and, without releasing Ctrl+Alt, pressing L to lock the screen * While dragging a window, lock the screen using the keyboard shortcut * While Alt+Tab-ing, lock the screen without releasing the Alt key In all cases, a window can gain focus after the screen was locked and all keyboard input goes to that window. Also, the window switcher remains fully functional and even shows the window previews like it would normally. It's even possible to open applications using keyboard shortcuts, for example a terminal. To enter the password and unlock the session, the password field needs to be focused by opening and closing an indicator in the lockscreen and then clicking the password field. While most of these actions aren't something a normal user would do, they clearly show that the new lockscreen is far less secure than the old one. The first trigger action is even something I've done in the past during normal use, switching to a desktop and then locking the session, so I would say there is at least a small "real" security risk in this.
