Hi, I tried changing it to OpenGL3.1 and OpenGL1 in desktop effects -
both times this triggered a kwin crash. Attaching the backtraces for
these (the kde bug reporter didn't think they were useful, though...)
I then changed it to xrender, as desktop effects module recommended (it
said that a crash had been triggered by my driver 'in the past') - this
seems to have got things working again (though 4 desktop effects are
still disabled, as these require OpenGL.
Cheers.
