Some of the Standard Assets image effects - example sun shafts - cause weird behavior in the Unity Editor, which doesn’t show up in builds. I don’t have a lot of experience, so I can’t say for sure, but my guess is that it has something to do with the shader changes in 5.3, since problem didn’t exist in 5.2.3.
Should I somehow precompile the shaders so they work properly in editor since the problem does not appear if I build the game?
Also, I’m running it on Mac OSX if that is in relevant in any way.
Here’s a photo to show the behavior.
