My GPU driver is OK.

I would say, no it is not okay. Its two years old.
What about that eye icon. I think it was no there before. How can I change it to the previous icon. I don´t know how it is called, bu it wasn´t the eye icon before. I know how to change it temporarily (Alt + clicking on the icon), but I want to change it permanently.
All of the panels in develop module have the eye icon. If you click on it and hold the mouse button down, you can temporarily see the photo with that panel's changes turned off. This has been present for several releases of LrC. If you want the previous icon, hold down the Alt key on Windows (I don't know what that is on Macs).
