VR Particles

I have downloaded the Unity particle examples (the new one) and I love the look of the particles. The trouble is, the very flat ones like heat distortion and flames are ruined by the billboarding. It would be one thing if they turned to face the camera on the Y, but they are tilting when the headset tilts as well, which may be the most immersion breaking thing I have ever seen. Does anyone know a way to get around this kind of issue?
