When will Apple fix the problem with Yosemite and the graphics driver for Photoshop users?

When using Photoshop the graphics will go haywire after just editing a couple of photos. They display with large blocks either rearranged or just white. Looking the problem up on the web I see it is a known problem and has been known since Yosemite came out. This really ***** because the whole reason I bought this machine was to work on my photos on the go. I have owned a lot of Apple products and usually swear by them. Maybe that's why I am so angry about this problem. I would expect better.
