Ran into this same issue in 14w21b, it seemed to be view angle dependent, here are two screenshots either side of the view angle that caused it.
This is on Ubuntu 12.10 (yes, that old), never noticed it on previous versions on MC. Graphic card info from glxinfo:
OpenGL vendor string: NVIDIA CorporationOpenGL renderer string: GeForce 320M/integrated/SSE2OpenGL version string: 3.3.0 NVIDIA 304.88OpenGL shading language version string: 3.30 NVIDIA via Cg compiler
