Title:
  OpenGL crashes KWin with 64-bit 3.13.0-21 kernel

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On my 64-bit installation, setting OpenGL 1.2, 2.0, or 3.1 when using
  kernel 3.13.0-21 causes KWin to crash. I'm forced to use XRender
  instead.

  This is also occurs using kernel 3.13.0-20.

  OpenGL 1.2 and 2.0 works fine and does not crash KWin when using
  kernel 3.13.0-19.

  On my 32-bit installation, OpenGL 1.2 and 2.0 works fine with KWin
  when using any of these three kernels.
