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.

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?
