           Summary: Displaying document with fit-to-width can result in
                    flickering scrollbar
           Product: okular
           Version: 0.10.2
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: jtappin at gmail.com


Version:           0.10.2 (using 4.4.2 (KDE 4.4.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.32-22-generic

When opening a document in Okular with the scaling set to "fit to width" then
if the window size is such that the height of the document needs a vertical
scrollbar when the scrollbar is absent, but does not need it when the scrollbar
is present, then the scrollbar flickers on and off continuously.

Easy way to reproduce it:
Open a landscape mode EPS (probably works with other formats as well) file with
Okular.
Slowly resize the window vertically until the vertical size is just too small
to show the whole page without a scrollbar
The scrollbar will then appear and disappear in an endless cycle until you
resize the window again (larger or smaller).

This works both with standalone Okular, and the embedded viewer in konqueror.
