I can affirm this bug, for my machines (about 4) this always happens (from breezy to gutsy).
Ihave attached my screenshot. If anybody want's to reproduce this, just open a big (or if you have slower machine enough if you open a little) pdf, and scroll that fast. The pages that isn't being rendered yet have a big X instead of the page's contents, that X's lines gets out and makes that lines... ** Attachment added: "kpdf lines over all" http://launchpadlibrarian.net/10112818/kpdfbug.png -- KPDF draws lines out of the window. https://bugs.launchpad.net/bugs/69406 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
