Summary: xpdf 3.01 bugs when zooming
Keywords:  
Status Whiteboard: 
Opened: 2005-09-12 14:56 0000
Description:   Opened: 2005-09-12 14:56 0000 
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.

Portage 2.0.52-r1 (default-linux/amd64/2005.0, gcc-3.4.4, glibc-2.3.5-r1, 2.6.12

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 ?

xpdf display bug.

------- Comment #3 From Jocelyn Mayer 2005-09-12 16:09:14 0000 ------- 
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.

------- Comment #4 From Luis Medinas (RETIRED) 2005-09-12 16:19:57 0000 ------- 
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.

------- Comment #5 From Jocelyn Mayer 2005-09-12 16:26:05 0000 ------- 
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.

Buggy partial display of a pdf page after having resized the xpdf window.

------- Comment #7 From P.L.Hayes 2005-09-13 23:42:27 0000 ------- 
I can confirm this bug. I had to revert to Xpdf 3.00.
