360 Video mapping distortion

Does anyone here have experience editing 360º video in FCPX? I'm fairly new to this, but I'm noticing that when viewing 360º video with mapping set to "Normal" the sphere that the video is mapped to appears quite jagged. You can see the issue in the light pole in the attached screenshot--the pole is kinked in the middle. It's as though the mapping sphere is faceted like a low-polygon object. I see this in just about every online tutorial and example using FCPX. The same issue is not present in other applications like Premiere. Anyone have any idea of what's going on or how to correct this?
