Hi All, was hoping latest update would have fixed this.
On a Macbook Pro Retina 15
AMD Radeon R9 M370X 2048 MB
I can view and do normal photoshop activity when the working window is free floating, but as soon as I drag it or view it in tab mode it blacks out, doesn't change with zoom, it appears in the navigator so I know im in the right position... and maybe you get a little refresh of partial image on the left... but thats it.
Has this been solved or is there a solution?
Looks like it could be a display driver issue. Go to Edit > Preferences > Performance and disable "use graphic processor." Then restart Photoshop.
