Depending on the driver (fglrx) and version that won't be possible.
You'll have to use:

KWIN_DIRECT_GL=1 LIBGL_ALWAYS_INDIRECT=0 KWIN_COMPOSE=O2 kwin --replace &

(that's O2 like OpenGL 2) but be aware that overriding the system detection may result in crashy behavior.

On a sidenote: the explosion effect is yet unmaintained and pretty much broken anyway.
