Description Steve McCall 2014-08-13 16:07:45 UTC
Created attachment 104573 [details]
Zip file containing example page, pdf exported with 4.1.6.2, and pdf exported with current

Problem description: 

Steps to reproduce:
1. Create frame 1 with wrap=through and option=background
2. Load frame 1 with background text for each page
3. Create frame 2 with background = white, transparency 100%
4. Allow frame 2 to overlap background text
5. Export to pdf. PDF/A-1a  _not_ checked.

Current behavior:
  When exporting to PDF, transparency on frame 2 is lost and background text is hidden.

Expected behavior:
  Exported PDF should show background text. 
              
Operating System: Windows 7
Version: 4.3.0.4 release
Last worked in: 4.1.6.2 release

Reproducible with attached file & also from scratch with: 4.3.1.1, 4.3.0.3

Not reproduced with 4.2.6.2, 4.3.0.2 

Notice there is UI difference in frame dialog box:
- 4.3.1.1, 4.3.0.3, 4.2.6.2 -> only have 'Background' tab
- 4.3.0.2 -> 'Background' tab splitted to 'Area' & 'Transparency'

Tested on Ubuntu 12.04 x86

right - at least since this LO-Version (4.3.0.4) LO does not honour the stacking of frames and not of the setting to transparency - result: Grafics are covered, even when these objects are send to top.
While frames with run-through give strange/unpredictable results on Export to PDF now - the more complex problems when exporting docs with transparency to PDF/A-1a are solved sufficiently.
so, export to PDF/A works, PDF does not

This is already fixed on 4.5 master and in 4.4.0beta1

A bibisect/bisect shows everything works correctly on master after the fix to bug 80468, but it seems that bug was fixed some other way on 4.3 which didn't also tangentially fix this bug.

If anyone is desperate to see this in 4.3, please add a comment and set the status of this bug back to NEW, but otherwise please just upgrade to 4.4.

-> Removing Whiteboard:bibisectRequest as there's nothing left to bibisect.
-> Setting Status: RESOLVED WORKSFORME (as not fixed on this bug, but not strictly a duplicate wrt 4.3)
