OS: Ubuntu 16.04.2 LTS
GPU: TITAN X (Pascal)
CPU: Intel(R) Core(TM) i7-6700K
Broken: 2.78 and 2.79
Short description of error
Lines of particles appear from -x to x from the mesh with a high-poly (69451 faces) mesh. After decimating the mesh the problem disappears.
Exact steps for others to reproduce the error
1 - Download a high poly STL (e.g. the stanford bunny (69451 faces) )
2 - Import mesh
3 - Add a particle system and emit from volume grid.
4 - Set emitter start and end to 0, resolution to 15, physics to NO and size to 0.005
5 - Duplicate
6 - Add a decimation modifier and decimate to 0.01 (693 faces) and apply
