ab6157aShort description of error
The size function on the bokeh blur node is somewhat buggy when in OpenCL mode. In variable size mode, if the scale of the input is below a certain amount, there is no blur at all. Also, using a constant size of around .150 turns the whole image blue. Neither of these issues appears when OpenCL is disabled.
Exact steps for others to reproduce the error
opencl_bokeh_blur.blend.zip
Open the attached opencl_bokeh_blur.blend, and hit render. Note the result. Now go to the node editor, switch on OpenCL, and render it again. Notice how there is no bokeh affect applied. To see the second bug, disconnect the math node from the size input, disable variable size, and enter 0.150 for the size value. The whole image is tinted blue. Disable OpenCL and both bugs go away.

I can confirm the difference of results. I'm on Linux, btw. For the blue effect, it appears if the size is between 0.079 and 0.156. Can't be more precise.

@LukasTonne, mind looking in this report as well? Thanks!
