Has anyone ever seen this on maps before?  The map comes from ArcGIS Portal hosted in a Web AppBuilder app.  I can't determine what the lines are associated with.  They are not a part of any layers.

Just some more information, I see the black lines show up on the actual tiles from ArcGIS Online server.

Here was one tile that showed the black lines.  The screen shot is from FireFox network traffic console.

The lines do not always appear.  It seems arbitrary.

Jordan, do you know what browser they are using? We have experienced the same here only on one system and only when running Firefox.

Thanks

This was caused by Fire Fox hardware acceleration.

Thanks for posting about this issue!  Do you know, is there any fix for this in FireFox, besides disabling the hardware acceleration?
