Offending transparency

I have various presentations where I set individual pages to a black background. Unfortunately, when showing the transparency on the screen, it is all black but a single white line at the bottom, which is very annoying. I attach an example and a screenshot (OS X Mountain Lion, but also on previous versions of the OS)

Comment 3 Roman Eisele 2012-11-08 08:15:56 UTC
Thank you for your bug report!

REPRODUCIBLE with reporter’s sample file and
LOdev 3.7.0.0.alpha0+ (Build ID: c1b407; pull time: 2012-11-02 23:47:02)
on a MacBook Pro with Mac OS X 10.6.8 (Intel).

However, I can NOT reproduce this with LibreOffice 3.6.3.2 on the same machine. This may be just some coincidence. Or is the Version picker wrong?

Good news: I hope that this problem could already be solved by Thorsten Behren’s patch:

http://cgit.freedesktop.org/libreoffice/core/commit/?id=b668d3aaf5690bd067c0ed283e9492ae576117f9

which was committed 2012-11-07 23:55:18 (GMT); so we need to test a newer daily build to find out ...
Comment 4 Juanjo 2012-11-08 09:09:13 UTC
I lowered the bug report version to the one I actually tested it with "Version 3.6.1.2 (Build ID: e29a214)"
Comment 5 Michael Meeks 2012-11-08 09:31:24 UTC
Thorsten - should we back-port your white-line fix to -3-6 ? :-)
Also - I have no recollection of changing that code myself ;->
Comment 6 Roman Eisele 2012-11-08 09:43:34 UTC
VERIFIED as FIXED:

While I can still reproduce this bug with
  LOdev 3.7.0.0.alpha0+ (Build ID: c1b407; pull time: 2012-11-02 23:47:02)
I can no longer reproduce it with
  LOdev 3.7.0.0.alpha0+ (Build ID: 88e457; pull time: 2012-11-08 04:14:44)
both tested on Mac OS X 10.6.8 (Intel).
So it is more than likely that Thorsten’s patch has fixed the bug:
http://cgit.freedesktop.org/libreoffice/core/commit/?id=b668d3aaf5690bd067c0ed283e9492ae576117f9

Assigned post mortem to Thorsten Behrens (to do the honours to him).
Comment 7 Roman Eisele 2012-11-08 09:44:52 UTC
I would like to second Michael’s suggestion of back-porting Thorsten’s fix
to 3.6.x, if necessary.

Thank you very much!

True - I was in error when accusing you, sorry. :)
Comment 9 Michael Meeks 2012-11-08 10:40:15 UTC
Oddly - the known fixed bug was filed vs. 3.6.x but the fix is a 3.7.x-only fix - ie. nothing to back-port.

JuanJo - can you confirm that your problem was with 3.7.x in fact ? :-)

Kendy- are you aware that fixing this white-line-at-the-bottom bug essentially reverted your:

commit 0a5b49e7199198974113dc2e8b68257b881fb9fb
Author: Jan Holesovsky <kendy@suse.cz>
Date:   Wed Aug 22 19:56:36 2012 +0200

    Seemingly off-by-one painting error in Impress' ViewShell.
    
    In fact, it is not a off-by-one, just the scrollbars do not align with the
    splitters; so adjust it to fit better.
    
    Change-Id: I062b5da6baf4c20bedbf69301066547dcd1ace20

:-) which created this white line at the bottom of each full-screen presentation. I guess that needs re-fixing.

Hi Juanjo,

can you please answer to Michael’s question:
> JuanJo - can you confirm that your problem was with 3.7.x in fact ? :-)

Else, we can get no progress about this bug ...

Thank you very much!

I am sorry but this is not 3.7.x I am using the latest release I know of (for some reason LibreOffice stopped showing me existing updates) which is Version 3.6.1.2 (Build ID: e29a214)

Ah -- so I have created the confusion by identifying your problem with the 3.7.x problem; I am sorry for this!

However, the confusion goes on: I can NOT reproduce the bug (i.e., I don’t see a white line at the bottom) if I open you sample file “2012-11-06-Semana de la Ciencia copy.odp” with LibreOffice 3.6.1.2 (Build ID: e29a214, the same build you used!) or 3.6.0.4 (Build ID: 932b512), or 3.6.2.2 or 3.6.3.2 ... i.e., with no 3.6.x version. See my screenshot: no white line at the bottom. The only difference is that I use Mac OS X 10.6.8, while you use 10.8.x, but this should make no difference.

So I am confused again. Is “2012-11-06-Semana de la Ciencia copy.odp” really the correct samply file, i.e. the one which should show the white line? Your sreenshot (attachment 69614 [details]) shows another file ...

Does anybody else see the white line when he/she opens the sample file with LibreOffice 3.6.1.2? (LibreOffice 3.6.1.2 is still available from
  http://downloadarchive.documentfoundation.org/libreoffice/old/
).

The bottom line either depends on the OS version or on the screen resolution. I have tested now on two machines:

1* A laptop with a small screen (1024xsomething) running OS X 10.6.2 and LibreOffice version 3.6.1.2 (Build ID: e29a214)

2* An iMac with a larger screen, running OS X 10.8.2 and LibreOffice version 3.6.1.2 (Build ID: e29a214)

System 2* is the one with which the screenshot was produced. The bottom line is vissible. System 1* does not show the bottom line.

Seems reasonable. More data: My screenshot (attachment 69899 [details]) was produced on a Mac Book Pro with Mac OS X 10.6.8 and 1680 x 1050 px resultion. But I still can’t see any white line at the bottom when I change the display resolution, e.g. to 1024 x 768 px or 1280 x 1024 px ...

(Another idea: is there some chance that some diplays, like my one, just cut off the bottommost horizontal line of pixels?)
Comment 15 Roman Eisele 2012-11-13 09:40:53 UTC
I have conneced an additional monitor to my MacBook (see prev. comment) and tried to ”present” Juanjo’s sample presentation on that additional screen like on a beamer. This worked fine, but regardless of the resultion I used for the additional screen (1280 x 1024 px, 800 x 600 px, 640 x 480 px) I did not see any white line at the bottom of the screen. It does not make any difference if I use LibreOffice 3.6.1.2 (as mentioned by Juanjo) or 3.6.3.2.

So resetting this to UNCONFIRMED for now. Maybe the bug really depends on the Mac OS X version (but IMHO this would be strange for a bug of this kind).

*** Can anybody else reproduce this issue in LibreOffice 3.6.x? ***
Comment 16 Emir Sarı 2012-11-23 02:47:35 UTC
Not reproducible under LO 3.6.4.1 and 4.0.0.0 alpha1 - OS X 10.7.5
Comment 17 retired 2013-05-31 09:50:29 UTC
Setting to WORKSFORME due to comment #16.

I cannot reproduce this problem with OS X 10.8.3 and LO 4.0.3.3.

@Juanjo: Could you please try the latest LO release (currently 4.0.3.3) and see if the problem persists. If that's the case, please re-open the bug and we'll further investigate.
Comment 18 Juanjo 2013-06-17 10:49:52 UTC
I can verify that the same white line appears with Version 4.0.3.3 (Build ID: 0eaa50a932c8f2199a615e1eb30f7ac74279539) on Mac OS X 10.8.4. I would include a screenshot but it is just the same as the one already in the bug report.
Comment 19 Thorsten Behrens (allotropia) 2013-09-12 16:14:39 UTC
Apologies for not having gotten around fixing this bug yet; unfortunately in future I'll have even less time at my disposal for this, so I'm freeing up ownership for other volunteers to take over.
Comment 20 retired 2014-12-11 11:09:59 UTC
10.10.1 LO Version: 4.5.0.0.alpha0+
Build ID: 6e91763769a562b88882a4c2a94b1367c6ed4866
TinderBox: MacOSX-x86_64@49-TDF, Branch:master, Time: 2014-12-11_02:24:05
Locale: de_

Does this persist for you with the latest nightly of LO?
http://dev-builds.libreoffice.org/daily/master/MacOSX-x86_64@49-TDF/

Also maybe by now you have updated to OSX 10.10.1?

what I see is exactly the screenshot Roman posted. No white line or issues for me.
