With continuous scrolling setting set to ON in the timeline audiowaveform continuously blinking

When you play the sequence with continuous scrolling set to on the audio waveform continously blinking as the playhead goes further, I know that it is caching and if you play that same piece again it won't be blinking anymore but this kills the point of the continous scrolling, and more over if you change the timeline scale of that same piece and start play it the audio waveform will blink again until it is cached
