Ulanzi Stream Deck D200 Causes Screen Jitter

[PacFlyer23]

I've been searching for a small plug & play ubs type keypad for just the 12 Function Keys - for use with the Comm Menu. I found a stream deck from Ulanzi - 14 buttons - D200 that wasn't too expensive. 

Got it to delivered and hooked it, downloaded the Ulanzi software app to program it and seemed to work great. However once in DCS missions, I began to notice an intermittent screen jitter when in the aircraft cockpit view. Unplugged the Ulanzi and still got the jitter. Then uninstalled the Ulanzi app, and DCS was back to normal. 

Strange how conflicts can be caused by what seen to be unrelated things. I'll be sending the Ulanzi back and still looking for a Function Key keypad solution.
