GPU rendering causes glass to become extreamly reflective Does anyone know how to get glass to be transparent. I'm using GPU render to render a bowl and cloth but the GPU and CPU final render have different results on the glass bowl 

The top image is using the CPU to render





the bottom one is the GPU.

Does anyone know why this happens and how i can fix it or work around it?

thanks for any help :)
If you have this issue and you are using an AMD graphics card, you can either use CPU rendering or try and fake a glass texture.

I've found that using glossy shader and transparent shader lookes pretty good:
It takes a little longer to render but i think it looks better than the glass shader.
