Only to the extent that it's not fast enough, which it clearly is given that iOS doesn't hardware-accelerate CoreGraphics. Anything done wrong can be bad, but flicker is really really bad. Pretty much only Apple gets it right in that regard (maybe Jellybean, I haven't used it much).
Apple gets it right because they cache prerendered textures so aggressively on the GPU. In this regard software rendering versus hardware rendering doesn't really matter much, since actual rendering happens so infrequently.
