I haven't seen this before and maybe it's a mac-specific OpenGL issue, but try adjusting the Near/Far Clipping Panes in the display options (d in viewport, under the Optimization tab).

I have many issues with the opengl display. Once you have an alpha attribute and transparency is enabled, houdini seems to not sort the primitives anymore and the viewport becomes a mess.

Do you have alpha on that geometry? I just always work with transparency off (display options, misc tab).

Cheers,
Koen
