Why does the rotation of the material on my Earth model shift in the viewport Material view? This one uses cycles and nodes I posted this question a few days ago; however, I couldn't get an answer. So I decided (at the urging of @Uncle Snail) to do one using cycles, but the same thing happens:
It looks fine in the Rendered view of the viewport. But I would like to see it in the Material view so I can edit it while the material is correctly displayed. Also, there is a bump map applied in addition to the material. The .blend file (with the packed files) is linked.
This was a bug, which is fixed in the version 2.78.
