Bug Description

Recently, when I resume from suspend I often can't input anything into the password field. After selecting an icon in the top left corner of the screen lock and then selecting the password field again I can type my password and unlock the computer. Once I do that whatever I typed in the password field actually shows up in whatever app had focus before I suspended, potentially leaking my password to a remote attacker if the focused app is a browser, as it often is.
