    <p>I was unable to reproduce this on a Ubuntu 20.04 system with
      ChimeraX 1.2.5.  So something weird is going on.   Please use the
      Help / Report a Bug dialog to provide us with information about
      your system.  And in your bug report, please include your 5byl.cif
      file (~/Downloads/ChimeraX/PDB/5byl.cif file if you didn't modify
      it).  There is also a chance that this is a hardware error, but
