Short description of error
Eevee nodes with vector input have a different default coordinate than what is used by Cycles. In blender 2.78, material draw mode, this worked fine.
Exact steps for others to reproduce the error
Then alternate between Cycles and Eevee. The scale of the brick texture is entirely different.
If you connect the Texture Coordinate node in the checker texture it works the same for Cycles and Eevee.
