In LibreOffice 4.2.x the master slide worked correctly by showing a single image in the header and no line. When opening the slide in the current LibreOffice version we get the image (logo of University of Bern) tripled and a blue line is added on the top.

Bodhi 2.x
LibreOffice bibisect (confirmed regression) existing still on release also exists on 4.4 built just a couple days ago: Version:
Build ID: 880c18f23068a1faf34f36a67161e3b85fffdea7

Normal - can prevent high quality/professional work
High - regression


Unfortunately it isn't bibisectable.

I see the same problem in master; 4.3.1.;;;
Latest version on my side that doesn't have the problem in

Is it possible for you to check that, Matthias?

The university logo image is tripled in the file, too.

<draw:frame draw:style-name="Mgr3" draw:text-style-name="MP3" draw:layer="backgroundobjects" svg:width="4.099cm" svg:height="3.151cm" svg:x="23.601cm" svg:y="0.349cm"><draw:image xlink:href="Pictures/2000000800000E2A00000AE39510764A.svm" xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad"><text:p/></draw:image></draw:frame>

<draw:frame draw:style-name="Mgr3" draw:text-style-name="MP3" draw:layer="backgroundobjects" svg:width="3.285cm" svg:height="2.535cm" svg:x="24.115cm" svg:y="0.6cm"><draw:image xlink:href="Pictures/10000000000004300000033BC55427E6.png" xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad"><text:p/></draw:image></draw:frame>

If you check the coordinates, you can see that they do not overlap exactly. The blue line also can be found in the file:

<draw:frame draw:style-name="Mgr3" draw:text-style-name="MP3" draw:layer="backgroundobjects" svg:width="27cm" svg:height="0.081cm" svg:x="0.5cm" svg:y="4.6cm"><draw:image xlink:href="Pictures/200000080000611A0000006687ED557D.svm" xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad"><text:p/></draw:image></draw:frame>

I cannot tell, if older versions were buggy, because they didn't show these elements, or the newer versions are buggy, because they show them. But there is a workaround: remove them from master slide.

Looks fine to me in current 4.5 master

    fdo#74124 bilinear scaling with blending for some formats
    The DrawDeviceAlphaBitmapSlowPath used fast/ugly scaling with
    blending. With this a bilinear scaling is used which should
    improve quality for downscaling (less than 50% should start to
    degrade in quality as only 2 samples are always used) and
