Graphics Driver Update 6.3 - External Display not recognized

Macbook Pro 11.5 (Mid 2015), Windows 10 Build 15063, Graphics Driver Update for Boot Camp v 6.3

After installing the latest graphics driver update, my external display (Dell U2415 via DisplayPort) is no longer recognized. Performing a system restore to roll back the driver update fixed the issue.

Anyone else see similar issues with this driver release? Is there a better way to alert devs to boot camp driver issues?
