[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.

Can you test the following kernels and report back?

v3.13.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.6-trusty/
v3.13.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.7-trusty/


Thanks in advance!

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.
