Huge speed drop with Amd GPU Pro

[BettyBoop51]

Hey guys, is there somebody who's using the latest amd gpu pro driver with the latest hashcat beta version confirm that the speed they get in rule-based dictionary attack is correct? I'd really like to know if the problem is on my side. Once again, speed is fine:

1) in brute force mode
2) in mask attack mode

It really has to do with the --rules-file parameter (tested many different ones, many different wordlists). Something looks broken.

Thanks !
