Cuda mining stops and cannot restart

I realized that when pool changes seeds cuda mining cannot restart.

you can simulate same error if you modify configfile while mining (something under cuda settings). If you started with cuda disabled the first enable perfectly starts but the next starts fail.

RandomX is not for GPUs for one you should be running it in a separate xmrig via MoneroOcean so as to process algorithms which GPUs are good at, and still be paid in XMR. Otherwise it's a complete waste of watts. It could be scoring more payout than the CPU does. (My GTX970 4GB is currently scoring 16.5KH/s XMR equivalence by mining cn/gpu at 700H/s)

Ty, it wasn't a question... I know it will mine me near nothing, but I can say it works and https://github.com/xmrig/xmrig-cuda/pull/125 will repair this issue... Thanks
