I tried to search for this, but couldn't find any other postings.
I noticed in V11 that when I zoom into an audio track, at a certain level of zoom, my waveforems change completely. The audio still plays back correctly, but what is shown on the timeline has nothing to do with what is playing on the audio track.

Has anyone else had this happen?

I found this as I was zooming in to line up 2 audio tracks. I noticed that one of them suddenly changed. Zoomed back out once level and it was fine.

This doesn't seem to happen all the time, but has happened at least once per project. I will try to recreate it on purpose and get you more details.
