I'm getting these artifacts in the viewport.
I'm running, mac osx 10.6.8, opengl 2.1, quadro fx4000, 18Gig RAM, houdini 12.0.641
Any idea on how to get rid of it?

Bug with the OpenGL viewer on the Mac when you use the OpenGL 2.1 option in the preferences. You can roll back to the old H11 gl option or bypass the Resize DOP.
I'd keep current with latest builds as well as there have been numerous fixes in the viewport.

For me I just create a default sphere, add the default Billowy Smoke tool and navigate to /obj and play with shaded mode on.
The viewport will display these artefacts for me on my MacBook Pro:
2.3 GHz Intel Core i7
8GB 1333 MHz DDR3 memory
AMD RAdeon HD 6750M 1024MB Graphics
Mac OS X Lion 10.7.4 (11E53)

Thanks, I can reproduce the problem with your file (but strangely not the default setup jeff mentioned, which was my first try). If I change the max size of a 3D texture to 32x32x32, the garbage disappears (Textures tab in display options), but the resulting quality is not really a solution. I'm thinking that it might be related to this:
Large 3D texture allocations can result in garbage data and possibly a crash of OS X (Bug ID 11226795).(from http://renderingpipeline.com/2012/04/sad-state-of-opengl-on-macos-x/) [renderingpipeline.com]
