Bugs

Hi! Very glad that the Fusion is now free. it's just a miracle.

Attempting to move the pipette when creating volume mask causes crash. Thanks for your attention

It works but not with GPU-acceleration. solution:turn off "Use OpenCL" in the VolumeMasknode.

Same with Defocus

You're going to need to provide more information. is OpenCL working in any other applications? What OpenCL devices do you have?

I have a GTX970 also have a GTX580,but i cant select it because of that am using the free version.
I suspect that if I could change to the 580 problems would have been solved.
Every thing is ok in Premiere Pro.

Try removing the 970 and see if that fixes it.
