I am finding that one possible show stopper is the gegl gaussian blur.

Here is a simple example. Open a 16bit, say 12 MP tiff image. Duplicate Layer, and run gegl gaussian blur with x=y=100. On my Macbook Pro with 8G RAM, either I will get vertical lines on the layer (at best) or crash my Mac.

Is there a way to speed up gaussian blur or is this a Mac issue and never happens on Linux?

Thanks,

Further information to my post. I built on Windows 7 64-bit and here I have 16G of RAM with dedicated Nvidia graphics. It crashes my video driver (which is able to recover) and then Gimp dies with this following. This is after graphics card recovery and then opening c2g.

Here is the error message:

Victor must have done some magic since he sent me an email saying that he was looking into the OpenCL bug. I can now say that this is gone and in fact GEGL is considerably more stable. I can actually work on 16-bit tiffs without crashing! :)

I was so excited about this that I rebuilt both Windows and Mac and posted on my website.

Thanks devs!
