Smeared objects above horizon line

I'm having a very strange problem in a project: When I add an image effect (any image effect) to the Main Camera, then objects above the horizon are smeared. See screenshot -- this is a test scene with just a default Unity skybox, two cubes, and a camera with an image effect. It happens in every scene with this project, even new/empty scenes, but only in that project. I'd rather not have to reconstruct the project to get rid of the problem. Anyone know what's going on here? Mac, Unity 5.3.1f1.

Oh, I also deleted the Library and reimported it, no better.

thanks

I exported the scene and imported it into a fresh new project. Same thing -- and in fact, it's even weirder: the cube is smeared upwards when above the horizon, but then as it gets closer to the top of the window, it flattens and the disappears. Here's a video. What the heck?!

 

And now it's happening in another project! I downloaded 5.3.1f1 all over again, still happens in there, with both projects now.

 

Thanks for the tip. Changing from Forward to Deferred does eliminate the problem. Hmm. I'm not too familiar with Deferred in 5.x but will read up on it. Does that give you any clues on the problem with Forward?

Oh, and I submitted a bug report yesterday, Case 763750.

 

Ah, got your email, thanks. Okay, I'll use Deferred until I can upgrade to 5.4. Thanks for the quick review and action!

 

I'm seeing this too. Is it a Mac only bug? Any ETA for a fix?

 

and switching to Deferred rendering works in the meantime in 5.3.

 

Cool, thanks.
