[Utkarsh Ayachit]

Yes, I am noticing that slowness too. Ken, mind taking a look at that?

For example, rotating the ring with a solid color, I get frame-rates  (from the annotation text) of over 100 fps with 4.4. With 5.0 I generally see about 20-25fps.  Do you see this too?

Now when you color by this array and then uncheck "Map Scalars", I get the attached images. I'd contend that 5.0 with OpenGL2 rendering is correct. In 4.4 it would just bleed some random color through for blocks with missing "Color" array. In 5.0, the color used is the "Solid Color" set before changing the array to color with.
