Screenshot of the presentation with the wrong pixels

On a presentation, when adding a border to an image it sometimes happens that there is one line of blank pixels separating the image and the border itself. I attach examples and screenshots.

Thank you for your bug report!

REPRODUCIBLE with LibreOffice 3.6.3.2 on Mac OS X 10.6.8 (Intel).

As far as I can see, if there is one line of blank/white pixels between the image itself and its border, and on which side(s) there are such white lines, depends on the zoom level (and on the screen resultion?).
* With some zoom levels, e.g. at 75% or 100%, there is no white line between
  image and border at all;
* with many zoom levels, e.g. at 76% or 106%, I see a white line at the
  right side of the image;
* on other zoom levels, e.g. at 50% (! there should be no aliasing problems
  at 50%), I see the white line both at the right and the bottom side
  of the image;
* on other zoom levels, e.g. at 61% or 65%, I see a white line at the left
  (and top?) of the image.

This is an old bug. When comparing different LibreOffice versions, I see some variation about where and at which zoom levels the white line(s) appear; e.g., LibreOffice 3.3.0 seems to show the white line mostly/always at the top or left side of the image; but nevertheless this bug is more or less reproducible since LibreOffice 3.3.0, so it may be very well be inherited from OOo.
→ Adapting the Version field (should always contain the 1st version which is known to contain the bug).


Could someone else please test if this bug is also reproducible on Windows and/or Linux?

I can confirm same behavior on LO 4.0.4.1 (Win7 32bit) with slightly different zoom level variations.

Still reproducible with LibreOffice 4.4.3.0.0+ built at home under Ubuntu 14.10 x86-64

Didn't find a workaround.
