Other instances of state creep i've found in the previous SDK version was leaving VBOs/IBOs bound, making straight-up client-side vertex array programs fail. Haven't tested if this problem persists in this version of the SDK as well.


Presumably this is why they're using a new shared context within the distortion renderer. Are you seeing state that's moving across that context boundary?


Are they? As I said, I haven't checked if the VBO problem persists with the new SDK, and I haven't looked into the source of LibOVR 0.4.3 yet at all.

My report of the shader program state creep was merely from outside observation: The simple fixed-function example program[1] I've written last month using 0.4.2 failed to draw anything other than the grey-ish framebuffer clear color after updating to 0.4.3, and when I added a glUseProgram(0) after ovrHmd_EndFrame, the problem went away. There are no other calls to glUseProgram anywhere as I wasn't using shaders at all.
