Preview Colors in project bin...

In this Beta version it appears that once you change your colour space, the previews of your footage are then oversaturated and not a true reflection of the footage. When you select a clip you do see the true reflection as you scrub through either in the fies bin or in the program view finder but the stills which act as thumbnails for each clip appear with false colours. 

I am converting to proxies and then using the REC 709 colour space for reference.
