My original issue was here: https://github.com/swimlane/ngx-datatable/issues/1599
So i actually know how to reproduce this one better:

Go here: http://swimlane.github.io/ngx-datatable/#row-details
open a few rows, then collapse them. 
Then hover over rows that were opened and adjacent rows.  
Sometimes it will just flicker, other times it will stay. 

On my mac I only saw the duplicate data
however on a Windows 10 i could see the black row (that was described in the other ticket).


note: 
someone found a temp fix: https://github.com/swimlane/ngx-datatable/issues/1594#issuecomment-439379643
but it is odd that you would have to do this.

Thank you for providing more feedback. Adding the requester to the cc list.
