Unplug your OTA Tuner from the Hopper 3 then reinstall it.
Whenever I unplugged the OTA module and plugged it back in before, it fixed the glitches. Unfortunately, they started up in a day or so.
I reset my Hopper 3 this morning, and while it was restarting, I unplugged the OTA Dongle. After the H3 came back up, I went into settings and set the Power option to show the last channel viewed (since my son always watches SportsCenter while eating breakfast before school

) but maybe I should use the SmartChannel option, just in case I don't reset the channel for him? Anyway, I went into the OTA section and it said to plug in the OTA module, which I did. The OTA Module detected pop-up appeared, so I selected Okay to restart the Hopper.
After my Hopper 3 started, I went into the OTA Settings, rescanned my locals (just for good measure; 20 channels detected), and tuned to my go-to acid test, 022-03 for our local FirstAlert 24x7 Weather sub-channel. It played for 2-3 minutes with no errors, so I channeled-up and -down to view the other OTA locals. Everything was solid, so I turned everything off and headed upstairs to my 4K Joey.
Same results, my OTA locals are glitch free. Today, so far, so good. We'll see what happens after tonight's restart.
