The blur effect isn't working on my machine. This has happened since I first tried it in beta1, and still happens on beta2. When I try to enable it, KWin has this to say:

kwin(2069) KWin::EffectsHandlerImpl::loadEffect: Trying to load  "kwin4_effect_blur"
kwin(2069): Invalid framebuffer status:  0 
QPainter::begin: Paint device returned engine == 0, type: 2
QPainter::end: Painter not active, aborted
QPainter::begin: Paint device returned engine == 0, type: 2
QPainter::end: Painter not active, aborted
QPainter::begin: Paint device returned engine == 0, type: 2
QPainter::end: Painter not active, aborted
QPainter::begin: Paint device returned engine == 0, type: 2
QPainter::end: Painter not active, aborted

...and I get no sweet blur effects. :(


Reproducible: Always
