Public bug reported: After resuming from S3 (suspend to RAM), KDE's screen locker briefly shows desktop/application contents before locking the screen, possibly revealing sensitive information to a third party.
Expected: The screen locker should block the view to the desktop and running applications instantly after resuming. Observed: Desktop/application contents can be seen briefly (usually less than one second). (Using libkscreenlocker5:amd64 5.7.5-0ubuntu1 on Ubuntu 16.10.)
