Description Andrius 2019-11-28 08:16:15 UTC 
SUMMARY
Memory usage is huge with certain (probably only large) PDFs. When the document is opened, OKular starts consuming ~8 gigabytes of memory. Note: I set the memory usage to "Greedy" in Okular

Okular will us as much memory as possible when set to Greedy, you can't complain it's doing that
Comment 2 Andrius 2019-11-28 21:06:45 UTC 
But it should only use the memory to load the document, what else is there to take up so much space?
