Video refresh issue after meeting ends

I've noticed an issue on my desktop, after any zoom meeting session is ended.  When a meeting is ended, the entire screen appears to refresh.  Meaning it flashes black for a half second.  But after the "flash" most of the screen remains black, with certain blocks of video visible.  As I move the cursor around, the screen will refresh and be viewable.  This is getting frustrating.  My company has removed/reinstalled.  Updated plugins and done most of the normal troubleshooting.  Cant get a good screen snip, as attempting that refreshes the screen, so that all is visible.  The only way I could get a picture of what is happening, if via my cellphone, which the company may not like.  Has anyone else seen this?  I've changed multiple settings and nothing has made any difference.
