Description Alex Holland 2004-04-19 17:12:27 UTC 
Version:            (using KDE KDE 3.2.1)
Installed from:    Gentoo Packages
Compiler:          gcc version 3.3.2 20031218 (Gentoo Linux 3.3.2-r5, propolice-3.3-7) CFLAGS="-march=athlon-tbird -Os -pipe"
OS:          Linux

I know there have been a lot of landscape problems, but this one seems to be new.

One of my courses uses A4 landscape PDF files. In KGhostview, these display incorrectly. 

1. They appear as portrait in the pager
2. The entire landscape page is displayed correctly, but when the page is turned using pgup/pgdn, only the section that would be covered by a portrait page is correctly cleared then updated. The remaining landscape section is updated without being cleared, so after looking at a few pages, this area is full of an unreadable mash of text.

I have tried other landscape PDFs without problems, so I assume it's something specific to these ones. However, Acroread and xpdf both display them properly, so I figured something had gone clonk on KGhostview's part.

I will attach one of the PDFs this report.

Another file with the same problem:
http://www2.bloc.org/archivage/plate_forme_ethnoculturel.pdf

dual-page US-Letter, has to be displayed in "reverse landscape" to be readable; paging or browsing document, as described above, only properly refreshes the "standard" area. 

Rezooming at same value (clicking 100% while at 100%) forces a refresh and page displays correctly then.

This bug has been in existence for as long as I can remember, and it is still present in KDE 3.3. I can provide a bunch of pdf files with this problem if necessary. As far as I can tell, pdf files that work first paint a white rectangle as background before they paint anything else. All pdf files that don't clean the background by themselves will suffer from this bug.

I also experienced this problem several times. Heres another file that is not displayed correctly when using landscape orientation: <http://pdf.euro.apple.com/pdf/pn=Cin_Disp30_report/Cin_Disp30_report.pdf>.

This works fine in Okular.
