I am using Mac OS Yosemite 10.10.5 and Lightroom version: CC 2015.3 [ 1052427 ]
Please follow the steps to disable the display adapter to check if it is causing any issues.
> Launch Lightroom
> Click on Lightroom > Preferences
> Click on the Performance Tab
> Uncheck the option Use Display Processor
> Relaunch Lightroom and check for the issue.
Let me know if this helps.
