If you set WORKAROUND_KWIN 0 this will fail on kwin but still operate correctly on \
every other WM (that I tested).
XReparentWindow causes an unmap of mapped clients, currently leading into \
releaseClient() This will (among other) eg. reparent the client to the root and this \
is (usually?) executed after the original XReparentWindow, so the client does not end \
up where it's supposed to be.</pre> </td>

I can not suggest to play around with the release code much (ie. ensure you've \
nothing important else on screen) Simply omitting releaseClient() will keep you ghost \
clients (not only in the compositor) and releasing but uncertain omitting of the \
reparent to root will get your windows lost (no more activatable yakuake) and playing \
