I think that the magnifier effect, and possibly others, is/are not compatible with opengl 3.1, I think that opengl 2 has the best compatibility level. Anyway the effect should fail to load without any crash. > 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. Are you using kwin or kwin_gles? I'm testing kwin and kwin_gles with glx and egl with two different intel card and it works for me. But, other users reported that using egl instead of glx fixed the issues. kwin_gles should be fixed in 4.11.7 (currently in unstable). To start kwin or kwin_gles with the egl backend you need to add .sh a file to your ~/.kde/env that exports the KWIN_OPENGL_INTERFACE=egl variable. I'm currently using a ~/.kde/env/egl.sh that contains: export KWIN_OPENGL_INTERFACE=egl If you are testing kwin_gles, please upgrade to 4.11.7. -- "If you optimize everything, you will always be unhappy." -- Donald Knuth Saludos /\/\ /\ >< `/
