Oh, now I see. Yeah, that problem need to be fixed, but don't know when I will return to MTP algo. Probably next week only, anyway will see, maybe will fix this sooner.

Thanks

What kind of rejects do you get? "Low difficulty" or "invalid job"? Try to reduce memory clocks or increase core voltage(if this a Vega card) to avoid invalid calculations on GPU. What about zero hashrate - that's because of MerkleTree generation on CPU, nothing can be done until I move everything to GPU.
