           Summary: forward dvi scrolls to wrong place
           Product: okular
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: DVI backend
        AssignedTo: okular-devel at kde.org
        ReportedBy: pascal.niklaus at unibas.ch


Version:           0.9.1 (using KDE 4.3.1)
OS:                Linux
Installed from:    Ubuntu Packages

I am using okular with kile and forward DVI. The behaviour of Okular deviates
from the one of the good old kdvi, and is flawed, in my opinion:

1) The paragraph under the cursor is not necessarily visible after okular was
called from kile. What I believe is happening is that Okular scrolls the
document so that the beginning of the page (actually the page transition) is
visible in the center of the window. This is not a sensible behaviour, since
the part of the text that one wants to see may be further below. It should
scroll so that the paragraph/line under question is visible.

2) Okular "rescrolls" the document on every call. kdvi was better in the sense
that it left the scroll position unchanged when the line to display was
visible. This allowed to work "interactively", changing the document in kile
and seeing the changes in kdvi without the text "jumping all over the place". 

For the moment, forward dvi is not of big use since one has to search for the
right part of the text all the time.

I think this bug is crucial since kdvi has been sacrified in the current KDE
version.

Thanks for fixing this.
