--- Comment #17 from Gregory M. Turner <gmt at be-evil.net> ---
Maybe it's to do with the particulars of my box but the patch from this bug
never quite worked correctly on my Gentoo box, Yichao (although I used it for
many months and eventually decided to just stop using Okular.

It /almost/ worked.  But certain actions --  I can't remember /exactly/ what,
but maybe it was something to do with scrolling past a page boundary? -- would
cause the display to go blank.  Under the hood everything was fine; if you used
the "normal" scrolling techniques then the document would appear again, but it
was as though okular did not realize that certain parts of the page needed to
be repainted.

Sorry I can't remember more precisely what the exact way to trigger these
problems were.  But I just wanted to mention it for the record, so that if
someone is looking into these patches with an eye toward refactoring or merging
them in some way, they should be mindful that there may  be some bug in there.
