@themightyoarfish The issue is because this is old documentation which is still located at the url

latest/tutorial/Advanced/pointcloud_outlier_removal.html#Prepare-input-data

The new path should be:- latest/tutorial/geometry/pointcloud_outlier_removal.html

The old paths were never deleted during change in paths of the documentation. Furthermore, since Open3D moved to furo theme (modern looks), I believe the CSS of the new theme is causing old docs to be rendered incorrectly.

See https://www.open3d.org/docs/latest/tutorial/geometry/pointcloud_outlier_removal.html where code is correctly rendered.

@ssheorey Tagging for action. AFAIK, this can be easily done manually.

Thanks for raising this issue; I've had exactly the same problem, I assumed it was some browser plugin I had breaking this. It was only when I tried the docs in other browsers and in ingocnito that I realised it was a bug in the docs themselves.

Its worth knowing that the "deprecated" versions of the docs (with the rendering bug) will often come up first in search results, at least for me. So when I use google to find documentation, a lot of the documentation I see has this issue.
