I have noticed that okular recently started breaking into a sweat when it |
| 10 |
renders pdf files. Even a four page document with a bit of colour and |
| 11 |
graphics seems to push the cpu: |

In case someone can interpret the content of the file: |

Once rendered, the CPU goes down to normal levels. The problem does not seem |
| 56 |
to occur when the pdf is just text, i.e. no photographs, or complex graphics |
| 57 |
in it. |

Other than the various top apps, perhaps you can try lsof? |
