This is not a bug. Displacements have a maximum luxel density based on the size of the displacement. Each displacement is limited to lightmap resolutions of 124x124. If you make very large displacements, you'll find that you cannot make small luxel sizes on the displacement. One solution is to split any large displacements into multiple smaller ones and then sew them together.

See Displacement for more information on how to create, edit, clip and sew displacements.

Confirm:This limitation exists in ; is it raised in newer branches of Source?

Note:A similar (less restrictive) limitation technically exists for brushes as well, but will only be evident on brush faces using materials with %CompileNoChop.
