Hello @andrucrypt
I`m having trouble with worksize setting. I think it has begun after dotnet-hosting-2.2.1-win installation but nothing changed after I deleted it. Couple of days ago everything was fine and worksize was at 0/256. Now it is "x"/1024. --opencl-launch=256x0 setting makes it 0/1024. With --opencl-launch=256x64 worksize is 64/1024 and miner solves correct shares but my rig is not so stable so I need to make it 0/256 again somehow.
I could just reinstall OS but maybe there is an easier way?

This is not a dot-net, it's Grin miner and its command
setx GPU_MAX_WORKGROUP_SIZE 1024... So use --opencl-launch 256x256 now(it should be same as default), or better 256x32 for RX580/RX570.
