There is a bug in plasmashell for Plasma versions < 5.9

A animation in the task bar (e.g. file copying) causes a high cpu load for
the plasmashell process. Because of this the system may become unresponsive.
The bug has been fixed upstream but it seems it will not be backported for
Plasma 5.8 by the folks at KDE. Users successfully backported this patch
several weeks ago and had no problems.
openSUSE Leap 42.2 (and probably 42.3) will stay with Plasma 5.8 since it is
a LTS release. Therefore it would be nice to apply the patch downstream in
openSUSE Leap 42.2.

We already have a very similiar patch (the workaround patch I posted in that
bug report) in the package. It does basically the same and I tested that the
solution accepted upstream is actually slightly worse in performance.
Thus there was no reason to take the risk and swap the fix in the package.

If you can verify that this bug is fixed in the KDE:Frameworks5:LTS repo, we
can submit it as update.
