When dragging to re-parent in the Outliner, I'm not getting any visual feedback. How do I fix this? In a video I just watched it looks like this:


But I never got this "Drop to Set Parent" overlay or anything like it.

I'm on 2.77a on Windows 10. Also never got this on 2.77.
What's wrong here and how do I fix it?

Thanks,

Chris
The problem is caused by the Window Draw Method in the User Preferences > System menu. When this is set to "Full", the overlay isn't drawn. Changing it for example to "Overlap" fixes the issue. (however, there are other problems that arise in other parts of Blender when Window Draw Method is not set to "Full")
