My pictures become wonky when I go to Develop tab

[MyManD]

I'm new to Light Room so forgive me if this is a "duh" kind of question.

I imported a recent folder filled with JPEG images from my D7100 (I like convenience so I forgo RAW shooting).

In the Library tab all of my images look as I expect them to, but when I choose one to touch up and go over to Develop, LR suddenly springs some kind of post-processing over the entire image, adding contrast to where I don't want it to and making all of the darker areas into a watercolor-esque pattern.

I've read other threads saying that Adobe strips all processing from RAW files and shows what the sensor saw when you do to Develop, but I'm not using RAW files. The program is taking my JPEGs and adding a layer or...something...on top and I can't figure out how to stop it from happening.

Any advice or help would be much appreciated.

Turn off the GPU option in the LR preferences on the Performance tab.

From what I can tell there is no Perfromance tab.

Please post the Exact version of Lr you are using. Go to Help > About Adobe PS LR or Help > System Info and post the exact version number.

Post a screen shot of what you are seeing in the Develop module.

Photoshop Lightroom 5.6

Here is an example at 1:1.

This is in Library view:

This is in Develop:

I'm guessing that you're on a Mac - this looks like a known bug in 5.6 that was fixed in 5.7.1. You can update from here:

Adobe - Lightroom : For Macintosh : Adobe Photoshop Lightroom 5.7.1 : Thank You

Holy smokes, that seemed to fix it! I guess it really does pay to stay up to date with the latest versions...

I truly appreciate the help!
