OpenCL uses your video card to perform certain operations faster but looking at the rest of your post I am not sure if this solved it.
Can you post a link to an image you created with ToBitmap? I am wondering if I can see the same behavior.
And what do you mean by 'my snippet is not what I've been using, returning that bitmap in using clause is in fact a runtime error.'? Returning a Bitmap should be okay as long as you are not using a 'using' statement when you create it. And the using statement in your post is for the MagickImage, not the Bitmap.
You don't need to install ImageMagick on your machine. All the code from ImageMagick is embedded in the Magick.NET library.
