That's what it sounds like.  If you are on Windows, check that your 
graphics drivers are up to date; on other platforms, you may also want 
to check whether OpenGL is updated.  And if that doesn't solve it, post 
details here about exactly reproducible cases that don't work, the 
version numbers of rgl, R, your OS, and your graphics hardware.  We 
probably can't help you if it's a driver/hardware problem, but others 
with the same configuration might be able to see if the problem is 
reproducible.
