PHOTOSHOP CC 2015 - Strange video issue while using second screen on MacOS

Encountered what appears to be a bug with the latest Photoshop CC Mac while using a second monitor. This happens even with Graphics processor box unchecked in performance prefs and all third party plugins turned off.

This has not happened with previous versions. This only happens on my second monitor, not on my Macbook Pro screen. When I drag the PS window around, the colors (of my image) on my screen flash. And sometimes the color in the color picker flash as well. Also, I opened a document and had a strange black box show up on my image. I zoomed in 1 level, it turned white. Zoomed in again it disappeared. Zoomed back out and it was back again. It did not disappear permanently until I zoomed WAY in and then back out. The color flash can be dealt with, but the black box obscured my image. I tried turning off all layers, but the black box was still there.

Running Yosemite. MacBook Pro (15-inch, Early 2011), 2.2 GHz Intel Core i7, 16 GB 1333 MHz DDR3, 2 Samsung SSD 500, AMD Radeon HD 6750M 1024 MB. Second monitor is HP LP2475W. Color calibrated using Spyder Pro 5.

I am up to date with the latest version of CC: "Encountered what appears to be a bug with the latest Photoshop CC Mac". There are no updates available from Creative Cloud.

Which specific version? CC is a couple years old. The current version is CC 2015.0.1.
