I'm relatively new to blender - I'm using version 2.79. I have been trying to render an animation using GPU with a Hilbert Spiral of 512x512. I keep getting an "Open CL error: CL_INVALID_ARG_SIZE" error message. I'm using an AMD Raedeon Pro WX 7100 card.
Are there some settings I missed (all I did was switch CPU to my card in User preferences and GPU in the render panel) or is it possible my card isn't supported by blender?
