I tried your sample. Absolutely no flickring stars. As expected as you 
use a sky_sphere.
BUT! If I stop the camera and ROTATE it like: rotate clock*y.

Doing that and I have flickering stars. Also expectable as you use a 
pattern scalled very small and have sub-pixels details.

In the sample, you definetely don't use a static bitmap, but a pattern.
