Any downside to running the pixel refresh function?

    I was doing some longer exposures last night and saw a nice green spot in a number of my images when I looked at some of the RAW files produced by my relatively new GX1 when using a shutter speed of around 1 second. I just happened to see the green when previewing in Adobe Bridge which doesn't do full processing for previews. The jpeg version doesn't show the green but those are camera processed and Photoshop/Camera RAW auto corrects the green if I fully open the image. RAW files taken with longer shutter speeds don't show the green although those are run through the in-camera processing so I bet that function eliminates them.

    My question is in regard to Panasonic's pixel refresh function. There isn't much in-depth information about this that I have found so far. Is there a downside to using this function? I found one brief reference that suggested you need to use your camera quite a bit to get the sensor warmed up before you run the pixel refresh. True?

    Any information would be appreciated.
