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! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1301570 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.
