Might have a bug.  I'm running a mixed rig of vega 64s and 56's.   The first gpu progressively loses hashrate while the others fluctuate up or down.  Restarting the miner puts the first gpu back up to where id expect it and it starts all over again.  Im on win 10 amd driver 19.1.1

Small update...the first card seems to settle down and stop dropping after a little bit.  It starts out hashing arpund 18/19 sols and then eventually drops to 14/15. After restart its right back at 18 again.

Im on the latest alpha release mining beam.
