Full Screen Playback Glitchy Lines

Hello, I have the latest premiere pro 2019 CC version installed and when I toggle full screen by using ctrl and ~ the playback shows weird intermittent flickering lines. This happens in full screen playback in premiere only. If I just play from program monitor without full screen the flickering lines aren't there. If I export the video and play it in full screen in windows media player there are no flicker lines and there is no issue playing the native media in full screen in windows media player either. This is all on the same monitor display as well. What is causing this?

My setup... I just built a Desktop which has Ryzen 9, 32 GB of Ram, 8 GB video card, and my work drive (where video files are) is an M.2 hard drive. This is very frustrating. Looks great during normal playback, but full screen forget it! 

I have the latest update CC for Premiere. And my files are recorded from Atomos Ninja V in the ProRes format at 4k 24fps 10 bit. Please, can anyone help?  Adobe, PLEASE HELPPPPPPP!!!!!!
