Summary: Most all pages go all black once enough pdfs are open Product: okular Version: 0.11.2 Platform: Fedora RPMs OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general AssignedTo: okular-devel@kde.org ReportedBy: benson.b...@gmail.com Version: 0.11.2 (using KDE 4.5.5) OS: Linux Inevitably, once I have enough pdf files open in okular, it will start displaying the next page I go to as totally black. Then the next and the next. If I hit f5 I get a few good pages, then back to black. I have to basically quite all okular instances in order for this problem to go away. Once it starts it infects ALL open pdf files. Reproducible: Always Steps to Reproduce: Open more and more pdf files in okular, and scroll around in them. Eventually, the pages go black. Actual Results: Pages go black. Expected Results: Pages do NOT go black. There are a lot of files open, some large, so one expects some degrading of performance, like slower rendering of the next page one looks at. But not that pages going black! I have 8G of main memory. I never had this problem on my old machine with 1G of memory, and as many large pdfs open. I would like to first know if anyone else has had this problem before I start specifying the particulars of my system in detail and trying to track it down. Maybe someone already has a head start. But I have seen no one having this problem. There seems to be a related problem related to X. Discussion in some other bug threads suggest that okular allocates a lot of memory in X itself to cache page renderings, and that it shares the memory among all open instances, and that it and X do not cooperate too well on freeing this memory, with resulting performance problems. My ears pricked up at hearing "shared memory among instances" because that might help explain how the black pages start spreading through all open instances.
