Horizontal dashes dashed lines on screen

Yep I have the same situations. For weeks now. Sometimes it just goes aways sometimes not. 

I had the black dashes occur out of no where a few weeks ago.  It was in a 1:1 meeting that I was hosting.  I was in gallery view and saw them on my guest, but not me.  We thought it was his account, in part because I had just gotten off a group call where I did not see any dashes (I was a participant not a host on that call).  Later that day I had another 1:1 that I hosted and saw the dashes, again on the participant not on me.  So then I started to think it was my account, like I was late on a payment, or my credit card failed (I recently got a new one).  But no.  My account is in good standing and this thing keeps happening.  I don't see it at all when I join someone elses call.  It happens sometimes in a group call that I host, but it's just one participant that gets the dashes...AND I've definitely seen the dashes come and go multiple times on the same call...again, always on the same person.  I've never had the dashes show up on my video feed.  Every time I search for a resolution to this issue, I see simple setting change suggestions, followed by comments of people saying that that suggestion did not fix their problem.  What is going on?!

And though I posted above that I thought it might have been resolved the issue persists.  I am all out of workarounds and combinations of features to enable/disable.  This is clearly a Zoom problem to resolve.  Anyone from zoom listening to us as we continue to experience this??

Same problem.  Started immediately after an automatic Zoom software update with no changes by me.  From reading this thread (and another similar thread on Zoom community), there does not seem to be a consistent solution that works for everyone. 

Who has time to randomly start unchecking, disabling and re-selecting Advanced Video options for each new Zoom meeting?  Hope is not a strategy.  Please fix this problem Zoom!

Same problem, exactly as shown in the picture. I was also told my paid plan doesn't offer support. This is more than distracting. I am using Teams more often.

Go into settings/video/advanced at the bottom of the screen and ensure that the second option for optimize the video IS NOT selected.
