Description postix 2019-10-31 17:12:02 UTC 
SUMMARY

For some unknown reason I sometimes observe that Okular utilizes constantly around 25% of the CPU in the background,
after it had stayed opened for a while and was not used.

It is not the first time that I experienced it, that's why I open this bug report now. Hopefully I can expand the report in the future with additional information.

STEPS TO REPRODUCE

So far, I had several PDFs opened, while one had unsaved changes and Okular was running (not a as backgroud job) but not actively used or focused.
