P: Image Size with preserve details gives bad results with OpenCL enabled

Hello, 

I bought recently a macbook and when I want to resample an image (from circa 25x25 cm/300 dpi to 50x50 cm / 200dpi), thing I often do, on the photoshop installed on the mac book, it doesn't work at all. You can see the picture transformed by this operation. 

When I do it on my windows computer, it works normally. 

Is there something checked by default ?

Is it a known bug on Mac ? on Photoshop ? 

I downloaded the last Photoshop version a couple of days ago. But the result is still the same.
