I'll wait for it. I hope that it will fix the problem I'm currently facing with my R9 380 to don't be used (though listed at the beggining, their hashrate stays at 0).
THX for the detailed info about your system. My crystal ball tells me you may have to do the following:
A workaround for rigs with mixed cards (Polaris and old cards): start two miners with "-di" option, one for Polaris cards and second for other cards. Use "-mport 0" option to disable port for remote management and avoid red message in second miner.
I will fix it soon.
I've found that solution by myself, but I'd prefer to don't have to run two windows, for the space it takes on the screen and for the ability to see the total hashrate in a single window.
