System Information
Windows 8.1 ATI R9 280x

Blender Version
Broken: blender-2.78.0-git.05b181f-windows64 but also tried the final

Short description of error
When I render a scene with Cycles and samples 1, the outcome is right.
But as soon I put the samples above 1 the objects in the scene start to fade.

This only happens with my GPU in Final Render with samples > 1.
The Livepreview is rendering fine.
The higher the samples the more faded the objects are

Exact steps for others to reproduce the error

Cannot confirm this here, but only have CPU cycles rendering. We need @Sergey or some other dev from Cycles team to test that with an AMD GPU I guess…

This is a driver issue then. There will be new drivers out at some point that will solve a lot of these random issues.
