Description Takashi Iwai 2006-03-07 14:34:40 UTC 
When the window size of xpdf is expanded, xpdf doesn't handle the displayed area correctly corresponding to the new size but keeps the old view area.
As a result, it shows broken (mixed) image when scrolled.

This problem didn't occur with xpdf on 10.0.

Takashi, please attach a screenshot for a better visual impression of the problem.

Comment 6 Takashi Iwai 2006-03-07 18:38:18 UTC 
This seems because of the check of ConfigureNotify event in XPDFCore.cc::update().
Removing this check solves the problem although this will keep redrawing during resize as an obvious side effect.

xpdf-3.01-resize.patch

What about this one? It still does throw away some events, and hopefully
doesn't miss the important ones.

Do you have a mbuilt package to test your patch?

Not yet.
