I installed the software update two days ago when it came out and found a huge major bug immediately.
When you Print to Video, you'll notice that the Kona will loose sync at random times. It looks like a blink on the screen but you'll loose video and audio for a moment and my monitor (Panasonic BT-LH2600W) will reset the screen. I do have a sync generator connected (AJA GEN10). This is a random event so pinpointing it will be very tough.
I had to uninstall the software and back down to the 6.01 software. Now everything is fine again. So..... That is a huge indicator that the Kona 6.02 software has an issue - at least with our edit stations.
