Default New cylinder to cube in 2.2 issue

In 2.2 I am loving the new cylconverter functionality so that I can show partial cylinders without needing to convert them to cube faces.

BUT. I have found it very difficult to get them to show without looking bent (wall lines look curved). I was sure it just needed the hfov and hfov parameters to be balanced, but no matter what values I try I can't get them to go straight.

Here is a typical example:

Here is the XML

The wall lines are curved. I am wondering, is there perhaps a minimum field of view that cylconverter doesn't like? All the panos I am using are <180 degrees.

Looks not bad.
But your image is not a real cylinder projection (looks like a flat projection). You can transform it to cylindrical projection using any stitcher software.
Another trick is to use "sin=0" parameter in <cylConverter> block. It removes sin compensation (causes less vertical distortions).
