If chosen via the UI or run via the command line, jupyter nbconvert --to webpdf will hang and CPU usage for chrome will spike to 100% if the DISPLAY environment variable is set.

From the cli, if I run unset DISPLAY prior to trying jupyter nbconvert --to webpdf everything works fine.

How to reproduce:

  1. create a new blank notebook named blank.ipynb (or choose an existing notebook)
  2. open a terminal on an OS that supports a DISPLAY environment variable
  3. run export DISPLAY=":1.0"
  4. run jupyter nbconvert --to webpdf blank.ipynb
