Problem with the camera and image effects?

hey, ive been trying out Unity's Image Effects for the first time and I'm having a problem when applying them to the camera on the FPScontroller - when i try to apply an image effect it does this:
i think this is something to do with the camera resolution but i don't know how to fix the issue - any help would be greatly appreciated, thanks in advance.

 

It does this with almost all image effects but at the moment i am trying to use the bloom effect, i just put the script onto the FPScontroller that has the camera attached to it. The only thing i have really changed is the lighting settings in my scene, which are below - i haven't played with the rendering mode unless its changed with the lighting.

This is how my scene is set up, its just a few different .obj files with different materials applied to them and some terrain underneath. I've also put a few point lights into the scene:

i feel like the issue is more to do with my camera settings or the screen resolution, as i tested out what happens when the window the game displays in is a different size and this causes the drag that occurs across the screen to either get bigger, smaller or move to the top of the screen instead of the right.

I hope this helps, thanks for getting back to me.

 

Just to add, i tried this in a fresh scene and the problem still occurs, I'm running the Unity version 5.3.0f4.

 

I looked into this further and apparently its a bug with Unity 5.3, shouldnt show up in builds so ill try and build a scene next time i have access to the project im working on - thanks anyways.
