Source/Program Monitor Mirror Glitching

Issue:
Both source and program monitors are behaving oddly during playback as if a glitch or bug, I'm not sure what. What it's doing is creating a mirror image of itself on either side of itself, consistently but at random times throughout multiple projects. Like a ghost that will not stop haunting me! hah.

For example, if I've loaded a multicam to source and hit play, sometimes I suddenly see a duplicate of the same source window (with obviously multiple angles of footage in multicam view) over where Program monitor is. It doesn't entirely cover it, just most of it. And begins to act laggy and strange when this happens and tips you off something is going wonky.

How to encounter the bug & Workflow: 
This admittedly might be trickier. I've created dozens of multichannel multicam using go pros and a main A/B cam angles (Sony FDR-AX100, can include a clip if you need!) but it's even doing it just with gopros stacked so camera doesn't seem to influence it.

Frustratingly, this bug glitch thing doesn't happen every single time I hit play, more like it happens randomly so could be once and not again for awhile - or could be that it sticks around while I hit spacebar toggling play and stop over and over. So I do suspect it'll be problematic to recreate but here's the report on it anyway.

Because we tend to load our multichannel multicams into source, this happens the most for me in Source playback, but occasionally with Program playback from timeline. When I'm playing direct from timeline to Program monitor, it'll mirror to the left now over where source window hangs out. The Source/Program monitors are side by side per usual in my layout by the way, so you can picture what I mean when I say to the left or right, and included a screenshot.

Steps for multichannel multicam:
All footage and audio get synced and labeled, then I create a new sequence, set it up to match framerate (29.97 in this case) along with it being multichannel, load it from the grouped sequence, then assign it proper channels and all that jazz. Then, I open it in source, enable multicam, and modify audio channels for mono for however many # tracks there are.

What was expected vs. what happened:
What should have happened is what we all expect, for everything to play as normal in source or program monitor without any weird mirroring duplicate windows occurring. And instead, that is what keeps happening to me! This has consistently gone on for days now. I've been in all sorts of projects, made new ones, hopped in already made ones, doesn't matter. I'm slowly losing a bit of sanity every day though and would love to get this solved! 

I do not have any third party plugins or panels installed presently to add into this mix.

I've attached everything I could think to send including the entire project, screenshot of it doing that mirror thing as described, a very overtired phone vid of me capturing it doing it live, and a quick spec on the actual footage for gopro and the Sony FDR-AX100 clip.

Please let me know if you need anything else. I did try to be thorough!
