Description linuxmaster 2010-11-16 05:39:51 UTC 
Version:           0.10.4 (using KDE 4.4.4) 
OS:                Linux

When using this pdf with forms,
http://www.ppt.gc.ca/form/pdfs/pptc054.pdf 
(passport application from the gvmt. of Canada),
after hitting <show forms> button, the form fields look fine and in place. But, once you scroll up/down using the mouse wheel or pgup/pgdn keys, all fields get misplaced all over the page. Some fields from other pages show current page also.
Document becomes unreadable. 
Form feature becomes non-functional.


Reproducible: Always

Steps to Reproduce:
1. download http://www.ppt.gc.ca/form/pdfs/pptc054.pdf 
2. Open with okular
3. Hit <show forms> button
4. scroll down

Actual Results:  
form fields get misplaced all over the page.
Document becomes unreadable. 
Form feature becomes non-functional.


Expected Results:  
form fields should scroll together with text on the page.

OS: Linux (i686) release 2.6.34.7-0.5-desktop
Compiler: gcc

I get the same problem with KDE 4.5.3 on openSUSE 11.3 (x86_64).  I will attach a form and a screenshot showing this.

Could the title of this bug please be changed from "From fields..." to "Form fields..."?  The misspelling makes this bug harder to search for.

Comment 6 jordonwii 2011-12-23 16:22:37 UTC 
Reproducible in Okular 0.13.3, KDE 4.7.3.
Comment 7 Albert Astals Cid 2011-12-23 16:55:22 UTC 
Fixed in 4.8.0, actually duplicate of some other bug that talks about the same situation with checkboxes or radio buttons or something. Anyway should be fixed with KDE 4.8.0, if not please reopen.
