The only time nnedi3 is used inside GradFun3 is with `resizer="lineart_rpow2"` or `resizer="lineart_rpow2_bicubic"`. Also, it is not called directly but within 4re's `nnedi3_rpow2.py`, so it would have to be changed...

>A quick and dirty way for you would be to add core.nnedi3.nnedi3 = core.nnedi3cl.NNEDI3CL right below of core = vs.get_core() inside nnedi3_rpow2.py. Or rather just change every occurrence of `core.nnedi3.nnedi3`....

Yes, `gpu-next` can be used for embedding with the `--wid` option, but not with the rendering API. My use case requires the rendering API, unfortunately.

Sorry for the late reply. Same behaviour when compiling with `amdgpu=0`, wrong usage and a system freeze after some time:  I'll try to bisect the kernel when I'm back...
