Same system, same hash, fresh build from JtR ( 146ce84b13e4137c15c04562fec1e80f87ac4803 ):

OpenCL platform 0: AMD Accelerated Parallel Processing, 2 device(s).
Device 0: Tahiti
Local worksize (LWS) 64, Global worksize (GWS) 524288
Loaded 1 password hash (Password Safe SHA-256 [OpenCL])

- Had to use LWS=64 because LWS=256 created a Zombie and I was forced to reboot :(
- GWS=524288 was the maximum for performance, GWS=524288*4 was the same speed
