Source file for export
A text field with transparent background created in LibreOffice Writer is exported to PDF without transparency. E. g. a text field with white background colour set to 100% transparency is exported as a text field with white background.

I did a bibisection with following result:

During the bibisection I also noticed, that the appearance of the text field in LO differed in broken versions (sometimes it did not show up transparent, sometimes it showed up with wrong colour). Maybe this is also related to this bug...
I can confirm the problem and the regression:
- works as expected in version 184.108.40.206.0+
- does not work in version 220.127.116.11.0+
- in master it is possible to get a correct pdf export but the frame parameters must be modified because of a different color palette and a different background filling management.
Each versions built at home under Ubuntu 14.04 x86-64.
Best regards. JBF
Maybe add this one to the MAB?
Also, I see some more ODF/transparency PDF-export problems - not looked at this thoroughly though.

Printed text field with transparent background
I have bad news - this problem appears while printing transparent text fields, too. As an attachment I have added a photo of a document with transparent text field and its printed version - the transparency is replaced by black background.
OS: Debian Wheezy
LibreOffice version: 18.104.22.168
Printer: Canon iR1020
Driver: Canon iR1020/1024/1025 UFRII LT ver.2.2 (grayscale, 2-sided printing)
Printed via CUPS 1.5.3
Sorry for the quality, I have only my phone here...
my Version: 22.214.171.124 on GNU/Linux Debian
I have tested this problem and found: Export to PDF or printing uses the transparency value only from 1% to 99%. But with 100% suddenly no transparency will be exported.
Workaround: instead of 100% use only 99% and all is o.k.
so let's set status to NEW
thanks for the workaround Joachim!
thanks for hint, but this is a pretty ugly solution. I have tons of old documents with "transparency" - just because in previous versions of LibreOffice there was an option "no backgroud" of text fields, which is now interpreted as 100% transparency. I can't check each document before printing or PDF export for the presence of such a setting and change each text field to 99 per cent transparency.

so you should consider downgrading to LibO 188.8.131.52 which is the stable branch and wait until the bug will be fixed in the LibO 4.3.x branch.
hopefully thank to your bibisect a bugfix could be worked out.
I put Bjoern Michaelsen on CC List to hear if he can do something.
Seems that Bug 83922 (PDF export of frames, explained), Bug 84294 (PDF export of frames, bibisected, proper example), Bug 85409 (PDF export of frames, example) and probably also Bug 83963 (PDF export and transparency of text fields, explained, bibisected, example) are the same.
I think that all except Bug 84294 may be marked as duplicates.
Since it cannot be reproduced with LO 4.4.0 master anymore, https://bugs.freedesktop.org/show_bug.cgi?id=84294#c8 suggests when it might've been fixed.
While in 4.2 and 4.3 on right click there is Frame-Background, in 4.4 there is Frame-Transparency. Question is: can the fix be backported to 4.3?
Feel free to reopen if not correct.
