I just upgraded to 1.0.6 and for the life of me I cannot get nanopool or suprnova to show my worker hashing. Using Win 7, R9 280x, and the following config:

ethminer --farm-recheck 300 -G -F http://eth-us.suprnova.cc:3000/user.worker1/50 --cl-global-work 16384 --cl-local-work 128

My GPU usage shows as 100% but in the output, after it shows "workloop 1" it always shows 0 H/s for the first .5 /s but then begins to ramp up. It never did this before. Any ideas what is going on?
