Jan 14, 2016, Error still occuring

Why is this closed ? It's still hapenning to a lot of people, and still happening today with last version.

I found that closing and re-opening unity fixed the error (or at least stopped it from showing up in the footer).

See logs attached:

Hi all.

Using Unity v5.4.
I came a cross with this issue after I implemented instructions from this video: https://unity3d.com/learn/tutorials/projects/space-shooter-tutorial/creating-shots?playlist=17147

Does anyone know what this error means and how to fix it?

Thanks

I'm also having this issue in 5.4.1f1

same, i get it always every time when work with unity, I hate this aRRRRRRGH

5.4.2f2

I get this error when I refocus on Unity window.
I tried changing layout to default and lo and behold, the Succeeded(hr) doesn't happen.

I pinned this down to closing project window tab on one of my custom layouts, but on another one closing SECTR Audio fixed it.
I feel like this problem has something to do with the window sizes inside unity, and not specific tabs per se.

The only default layouts that give me this error are 2 by 3 and 4 split.
In the 2 by 3, the problem goes away by closing either scene or game view windows.
In the 4 split closing 3 of the 4 scene windows or everything else than the scene windows, does the trick.

In any case, I think going to default layout, or building a new layout from that as base, will fix it temporarily.

I had this problem recently.
It disappears after activating the options in "Forward Rendering Options" (Specular Highlights and Reflections) in one of the materials I have on the scene.

I re-started Unity and the message is gone.
