This packages provides 2 additionals patchs from upstream :

- patch405 to fix kde #261704 ( Fixes disabling fullscreen for windows using two displays)
see https://bugs.kde.org/261704
- patch406 to fix performance issue in kde ( replace non-const QVector::operator[] accesses with const ::at() to avoid many deep vecor copies) 
This patch is asked to backport by the kwin maintainer.
it should *really* increase performances with kwin when there's several open windows
«  know it is unusual to point to a bugfix on the kde-packagers mailinglist, but this is a rather important 
performance improvement for a bug present since 4.0 in KWin.

During working for an optimization in 4.8 we noticed that we do deep non-const vector copies where a const 
at() operation was expected. This means that we have in each frame:
4x+5xy unneeded copy operations
(x == number of loaded effects)
(y == number of windows).

These copy operations explain the finding by Owen Taylor that KWin's performance correlates to the number of 
open windows [1]. I did not retest with just the bug fix, but after my optimizations for 4.8 [2] this behavior is gone 
(my curves are unsteady, that's why I have not published them).

I would appreciate if you provide this patch to all your kde-workspace packages, no matter which version. The 
bug fix can be found in the kde-workspace repository in the KDE/4.7 branch as commit [3]:

Advisory :

« This package add more additional fixes for kdebase4-workspace fixing a bug with fullscreen in twinview (kde #261704), it should also improve kwin performance when a lot of windows are open »
