When building with an openGL core profile(GLFW_OPENGL_CORE_PROFILE), I'm getting a driver crash(NVidia 347.09) in glDrawElements on dismissal of the HSW while SDK rendering(between ovrHmd_BeginFrame and ovrHmd_EndFrame). The client path works fine and the warning can be dismissed while using that path, but the crash occurs on a switch back to SDK rendering. Running in a compatibility context the crash doesn't occur.
in both Direct and Extended display mode in both Debug and Release modes in VS2010 Express NVidia 780Ti, driver 347.09
*Edit* After more testing, I can provide some more info on this.
In a GL core context, Calling GLError() yields a GL Error: invalid operation on the first VAO bind after calling ovrHmd_DismissHSWDisplay on both AMD(HD 6670) and NVIDIA(780Ti).
In compatibility context, The NVIDIA driver seems to let this one through and everything works fine. On AMD, I see smearing on any pixels that haven't been written to by scene's display(i.e., the black background from the glClear(COLOR|DEPTH) done on the render target).
