this could be bug #243991 as well ... but in doubt, try to "disable functionality checks" ("kcmshell4 kwincompositing", advanced tab)
The checkbox is already checked. I've tried disabling but that makes no difference.
try to call "LIBGL_ALWAYS_INDIRECT=1 kwin --replace" and grep ~/kde/share/config/kwinrc for entries "safe" - "OpenGLIsUnsafe" should be "false" (this marks a detected crash due to broken drivers while attempting to set opengl and prevent further crashes by skipping such tests)

I've chnaged the OpenGLIsUnsafe to false and run "LIBGL_ALWAYS_INDIRECT=1 kwin --replace" and Opengl is working again.
