I had exactly the same thing happen to me on two different machines
(F20, KDE, KDM, 64bit, but different graphics --- Intel vs. nVidia).

It's the kernel.

If you boot into 3.13.10-200, everything works. If you boot into the
latest, 3.14.2-200, desktop effects are dead and kwin works only in 2D
regime.

I don't know what is wrong, why it happens or who is the culprit, but
it appears to be kernel-related.

I'll keep booting into 3.13 until this gets sorted out... ;-)

HTH, :-)
