waveforms morph/change/are regenerated when seeking

Description
I'll attach a screencast, this is really strange. When the playhead moves, sometimes the waveforms under it are transformed. This tells me two things:
- there is something flawed in the way they are calculated, since they are calculated differently the second time
- there might be an ugly iceberg underneath this. Why is it "showing" this symptom? Doesn't that mean that it somehow tries to recalculate waveforms all the time when the playhead moves? If so, isn't that a performance problem?
By the way, this also happens when rendering (since the playhead moves by itself at that time).
It may be more apparent with certain waveforms/clips than others.
