Taken in the lockscreen

When you press Ctrl+D ('Show desktop') all open windows will move to the four corners of the screen and half opaque, so that the user can see what's on the desktop.
Locking the screen in this state does not cover up this effect, resulting in readable parts of open windows although the screen is locked.

STEPS TO REPRODUCE
1. Open at least one window.
2. Press Ctrl+D to show the desktop.
3. Press Ctrl+L to lock the screen.

OBSERVED RESULT
Lockscreen does not cover the open windows.

EXPECTED RESULT
No windows, just lockscreen.

I recall that this is a very-recently-fixed KWin bug but I can't find the one to dupe it to.
