I updated xpdf to version 3.01. With this version when zooming a page and moving (with keyboard cursor keys) inside this page, only a part of the display is redrawn. It seems that only an area corresponding to the original displayed form (ie the area displayed before the zoom) is re-displayed. I did see this bug on two machines, one amd64 and one x86. Reproducible: Always Steps to Reproduce: 1. Open any pdf file 2. zoom it 3. move inside the displayed page. Configuration of the tested amd64 machine: Portage 2.0.52-r1 (default-linux/amd64/2005.0, gcc-3.4.4, glibc-2.3.5-r1, 2.6.12 x86_64) =================================================================

i tried to reproduce the bug and it's everything ok with it. This happen when you maximize the whole window ? Which wm are you using ? You got the crash with all pdfs you have ?
Created attachment 68306 [details] xpdf display bug.
There's a fact I didn't notice at first: it seems you need to resize the window to make the bug appear. I can reproduce it on any pdf. I'll join a partial shot of the display of a part of the PCI specification (random example). On this example you can see two parts, on the right (grey area) and the bottom (broken text) that have not been redrawn when moving inside the page.
yes i've seen the crash can you please add a backtrace of the bug ? I will try to get some info on the upstream for now.
I don't understand what backtrace you mean ? I did not had any crash of the program, only display bugs. Can you precise what you mean, please ? In the meantime, I did make more tests. Then it appears it's in fact a resize bug. I've got another shot that shows the problem: This time, I just reduced the window. Then, it's well drawn but I cannot move into the page to see the parts that are not displayed. And one can see the scrolling bars "pretend" the whole page is displayed. As I still have some window opened with the previous version running (ie 3.0), I can confirm that this bug appeared with the latest xpdf version.
Created attachment 68310 [details] buggy partial display of a pdf Buggy partial display of a pdf page after having resized the xpdf window.
I can confirm this bug. I had to revert to Xpdf 3.00.
Confirming this for ppc as well. Using ion3-20050820
the bug has been fixed by the author and i am attaching the patch....... som1 plz update this to portage asap.
Created attachment 70037 [details, diff] Patch from the author sorry forgot to attch with ladt post
I added the patch to xpdf 3.01. Please upgrade to xpdf-3.01-r1 Thanks for the reports
Seems all-right on amd64. Thanks.
