Depending on the "background colour" (white, light grey, dark grey etc) I choose, the image in the center, where I apply all adjustments, changes. And there is always this weird colour effect on it. You can see, that on the right, the picture is shown in a normal way.
I use Lightroom CC (2015) on a PC. I did not use any presets.
Has anyone of you a solution to my problem or has had the same problem? Thank you in advance for your help.
Turn off the GPU in LR / Edit / Prefs / Performance - uncheck Use Graphics Processor.
Thank you so much! I didn't know it was so easy to resolve.
