System Information
Operating system: Windows 10
Graphics card: nvidia

Blender Version
Broken: Version 2.80 Beta
Worked: Yes, besides this, it works pretty well, other than the occasional crash.

Short description of error
I built a house in the picture, but when I switch from EEVEE to Cycles it's as if the house moved, when it didn't.cycles.png
You can see here that the smaller section of the house seems to have shifted upwards somehow. Up and to the right side of the screen, intersecting with the other section. It tidn't happen with the other one, which isn't unwrapped properly.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file. I shaped a few default cubes, including adding booleans where the windows are. Then I unwrapped them and added the brick image textures. After creating roogs, and tweaking with the shaders a bit, I started sculpting the sides of the house to add more realism. Then I unwrapped the smaller section of the house again, because I had added new geometry when I sculpted with dyntopo. so the brick textures were no longer there. I unrapped using the cube projection. Then I switched to rendered view, and changed to cycles to get a more realistic preview. And that's when the [picture happened. When I switch back to EEVEE, the house is where it belongs, and when I'm in solid view in Cycles, it's fine too. Only when I'm in Cycles AND rendered view, does this problem happen.

I'm sure others have reported this bug and you may already be trying to fix it. I also understand that you have a lot of work to do and a lot of other bug reports incoming all the time, since 2.8 is still in Beta, so I don't expect a responce. I'm just doing my duty to the blender community, and I'm excited to see when 2.8 will be ready for official release.

What happens is that Cycles is doing actual displacement of the mesh vertices. You can fix this by going to Material > Settings > Displacement Method and using Bump Only.

We have recently changed the default to Bump Only to solve this confusion.
