Does anyone have the issue with Nicehash on these new miners when cards seem to be working, no HW errors present but no work being accepted either? I only get two lines repeating ad nauseum in the client: "Pool detected new block", followed by "Work restart requested".

Drivers are 14.4, cards are 270/280/7950 and the first Darkcoin release of the X11 works with Nicehash without issues. Since the old client works and new does without HW issues, I can't see how this could be a driver issue.
