Canon Powershot S120 Adobe Lightroom RAW converter problem

Question

Have a MacBook running Yosemite. I am an underwater photographer so rely on using White Balance to get colour into my photos. Since upgrading Lightroom from 5.3 or 5.6 to 5.7 all my Canon S120 RAW files change colour after import and become a wishy washy green.  As one moves along the filmstrip, the Histogram shows calculating and all the photos lose their colour, as if the White Balance is being removed. My previous catalogue, same camera, Lightroom 5.3 or 5.6 photos import as they look on the camera. Have discussed with Canon and they think an Adobe Codec RAW converter problem. Do you have additional Codecs for Canon S120? Canon happy to discuss problem.  Their reference: 1-3374995525. Please help.

If you look at the Tint slider with As Shot WB set, you’ll see it is maxed out at 150 for all three of your sample images. 
I think this means that LR’s DNG Profiles don’t have the range to entirely neutralize the WB so your images are left with the wrong WB and no way to fix it. 
Adobe profiles don’t do a good job in extreme lighting situations, especially with an overabundance of blue light which underwater pictures typically have.
You can mess with the Calibration sliders a bit and get some of the colors to be more like the camera-JPGs have, but some colors will still be different. 
If you have an X-Rite color-checker, that you could photograph without getting it wet, then you could make a custom camera calibration profile for that specific lighting scenario and maybe it’d work, but maybe the profiles still can’t extend beyond a certain point.  I am also not sure how you’d keep the color-checker dry underwater.
