Bloom/Glare doesnt work with Cubemap/Spherical/Cylindrical cameras

[SaY]

Bloom and Glare effects are currently being applied to the entire image, overlapping the seams of the images then  the Cube/Spherical/Cylinder camera projection is used.

I think this should be fixed in next daily build: https://forum.corona-renderer.com/index.php/topic,14143.msg90955.html#msg90955

The solution in the meantime is to add a CShading_Beauty pass to your Render Elements and make sure that "Apply bloom and glare" is unticked. This will give you a pass that you can use to feather out the problematic areas of bloom and glare in post.
