I was trying to stretch a guitar note as shown in this video https://www.youtube.com/watch?v=ArEPtQ9tQfA but instead of stretching, it seems to reveal the trimmed bit. You can see before and after stretch pics below.
In fact, I tried that. It must have been late or I'm just too stupid. What fooled me was the waveform picture looks like it doesn't change and it appears there is no sound after a point. The sound does go on though. I took some screen shots. You can see what I mean. It sounds right though.
Bringing up other windows doesn't redraw it in my case. I tried closing the Main window and reopening it, but I hate doing that. Every time I do that, it moves the main window to a second monitor and gets rid of the view I had, so I have to go back into Customize Control Bar again. (I like to have the locator values visible).
Anyway, the sound is right. I hope they fix that because looking at it is disconcerting.
