Bug#587809: kde-window-manager: Fails to display windows correctly when leaving full-screen

[Thue Janus Kristensen <thuejk@gmail.com>]

Package: kde-window-manager
Version: 4:4.4.4-1
Severity: normal

I have a dual-screen setup.

When I 
1) put a kaffeine window into fullscreen (by double-clicking on it)
2) then leave fullscreen again by double-clicking on the kaffeine window

Then the other windows behind the kaffeine window, which should now be visible, are not correctly displayed.

I recorded the error occurring here, using a maximized konsole-window as background.
