           Summary: okular is slow when scrolling dvi files
           Product: okular
           Version: 0.8.2
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: vigleik.angeltveit at gmail.com


Version:           0.8.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.28-11-generic

When viewing a dvi file and scrolling from one page to the next, okular pauses
for approximately one second while loading the next page, unless that page has
already been viewed.

This happens even with the 'aggressive' setting for memory usage. I see no
reason why okular can't preload the whole file unless it is very big.

kdvi performed much better, though it no longer seems to be in the ubuntu
repositories, so I can't make a direct comparison.
