Microsoft Teams - Purple, black, and green lines on users video feed

When using Teams on my Chomebook I have recently started losing the video of certain members of my team.  Their image is replaced with a variety of green, purple, and black lines which completely cover the part of the window where their video feed would normally be shown.  The audio remains unaffected.  It is usually the same team members affected every time, and only usually one team member per call is blanked out.  

I have fully updated the operating system and Teams itself.
