A/OpenGLRenderer: Error: Ambient Index Buffer overflow

I've got a card flip animation between two fragments that crashes out mid animation. I've tried setting a break point where the animations occur (New to debugging animations, let me know based on my code below, where I should be setting the breakpoint), however I haven't had any luck a pinpointing the culprit. The only error messages I get when the app crashes are as follows:

A/OpenGLRenderer: Error: Ambient Index Buffer overflow!!! used 300, total 298

I followed tufekoi's solution and changed my root layout from cardView to FrameLayout and it worked, that simple.
