V12 time squeeze artifacts

Has anyone noticed that when time squeezing in V12, there is an artifact in the audio that sounds like a delay? It doesn't matter how much or how little, it is in every time squeeze event. I took a clip into V8 and it is clean as a whistle at 108% but I can not squeeze at all in V12 without this problem.

Is there a setting that I need to adjust?

I have worked around this by taking unsqueezed audio into V8, squeezing it and bringing it back into 12 to replace the badly squeezed audio but this is a PIA.

edit: this is build 563. Don't know if this problem was in previous v12's I just noticed it yesterday.

Thanks,

UPDATE: Time stretch works great. No audio artifacts at all but time compression (ctrl-click drag to the left) definitely causes this anomaly. It's not just a preview thing either. It gets rendered into the file.

Can someone else check this for me? I need to know if this is my system or a bug. I've checked and changed every preference that I can think of and it has not made a difference. Again, V8 works fine on the exact same footage.

I finally got an answer to this from Sony. Thought I would post it here for others reference:

Vegas Pro 12 should include elastique time stretching tools for audio events, but it may be turned off or set to a lower standard on your project. To see if this is the case, put an audio event on the Timeline and stretch it. Then right-click the event and choose Properties. Under the Audio Event tab, there should be a section labeled "Time stretch / pitch shift" with a drop-down menu for "Method." Make sure this is set to elastique.

Once you select elastique, you should have a second drop-down menu for "Stretch Attributes." On my own sample project, the "Efficient" setting was not much better than "Method: None." However, the other settings were much better. Try adjusting these settings to improve the quality in your project.
