Screen-Space Camera on canvas causing scene to go blurry

Hi, I am having an issue regarding my canvas and camera setup. If I set the canvas to use ‘Screen-Space Camera’, the whole scene goes blurry. The only way I have found to fix it so far is by turning of post-processing on the camera. I can’t figure out why post processing is affecting the bluriness though. I have tried checking the tick boxes for every post processing override but none seem to be contributing. I created a new unity project entirely and cannot recreate the issue, it seems to work and is only specific to my other project. Is there a setting somewhere that could be causing this issue?

Thanks,

Dan



Images with and without post-processing turned on in an empty scene. Vignette seems to be applied even with no post process volume in the scene.

After some testing I have found that even with nothing but a camera in my scene, enabling post-processing on the camera causes post-processing effects to be applied to the scene. It seems to be pulling the post-processing from another scene I have setup with a simple vignette. I tried making the volume local only but it is still pulling the effects. This also still does not explain the blurr, as my other scene is not blurry
