Bug ID: 396137 Summary: Okular hangs when scrolling fast on both pdf and djvu documents Product: okular Version: 1.4.2 Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: major Priority: NOR Component: general Assignee: okular-de...@kde.org Reporter: maxim.starga...@gmail.com Target Milestone: --- Fast scrolling through large pdf or djvu document sometimes causes okular to fail to display content of the pages from some point. It just sits consuming 100% CPU time, pages content never displayed (empty white pages are displayed with okular logo in the left upper corner). Meanwhile interface remains responsive and pages, rendered before the hang occured, are still displayed when you scroll back. Okular does not actually crash, it just hangs, endlessly running at 100% load. Most often can be reproduced when holding PgDn(PgUp) continuosly for some time so okular is forced to go very fast, skipping pages. Sometimes it occurs when you type in some page number from the middle of the document and go directly. This bug is much easier to reproduce when processor is heavily loaded in background (i.e. building stuff). In that case it could be reproduced almost every time with any large document. When system is idling it still happens sometimes but you have to try for a while. -- You are receiving this mail because: You are watching all bug changes.
