Adding audio clip invalidates timeline preview render
Just noticed this... Before, changing stuff on the audio tracks did not invalidate the preview renders, and so one could happily add channels, move audio around and add special effects and so on, and as long as you did not touch anything that would change the video the preview render stayed intact.
Now, if I do a simple audio recording, the preview render is invalidated. Surely this is non-intentional? Is the whole point of the preview render not that it is video only?
