Black bars over text in finder window

I'm getting horizontal black bars over text in finder windows in High Sierra. Anyone have a solution or cause. Apple tech support is clueless...

Mac Pro, macOS 10.12

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?
