I have just installed the latest version of Photoshop 2017.1.1
I haven't changed any system settings on my iMac or in PS prefs.
When I make a global change like distortion or colour balance the screen does not refresh so it looks like nothing has been applied.
Only by maybe changing view size or closing and re-opening do you see the change.
This is very annoying and disconcerting making workflow very slow.
Has anyone else experienced this?
