I think it's a problem with how the miner and wallet display solo mining shares. The miner shows the share was found (block) and the wallet shows the block was submitted, but the transaction was never confirmed because it was an orphan. If you check the transaction list in the wallet there should be no transaction listed.
Yes, there are no transactions, I've checked it on block explorer too. This just confused me :/
I start that miner you sent and it's great I've got 10MH/s more on total. Thanks. Majoh done good work, do you have also source codes? I can't find them. I would like to compile it with CUDA 9.
