I am lately having issues with one of my cards (R9 270) displaying zero earnings in the daily graph for one or more 10-minute intervals. It might run for a day and then there are some gaps (zero profit). I have reverted the frequencies back to default, rebooted and even cleared the benchmark data, but it appears again and again.

I have submitted a report and wait for the answer....

Also, i noticed that it switches to GBX coin for no reason, reporting a false high price for 5 minutes and then it drops back to normal, so it changes back to ubq or xmr. This happens a lot of times during the day. Can you please fix these erroneous changes? Maybe increase the time that a coin has to sell high in order to be selected in winminer?

Thanks a lot.
