I've been using strict masks when generating mesh with depth maps since they were released. But the last 2 pre release builds of 1.6 and the 1.6 release have that setting greyed out. I've tried reinstalling and resetting all settings, but can't get it to enable again, and don't see anything in release notes. I'm using standard if that matters, is this a pro only feature now? It's not just one image set, it's every one since the last 3 builds.
Some other details:
Recently added a 5700 XT as main card.
Using 16 bit tiff.
