slide used to reproduce the issue and a picture showing current behavior (for control check).
I was working on a slide today containing three textboxes aligned next to each other. However, when saving to *.pptx and opening the *.pptx again in either libreoffice Impress or Powerpoint, the textboxes would overlap each other resulting in an akward look (see the picture in the zip file).
Steps to reproduce:
1. Open testslide.odp
2. Save testslide.odp as testslide.pptx
3. Open testslide.pptx
The text overlaps and results in a different look when reading the *.pptx file in comparison to the *.odp file.
The *.pptx file should look identical to the *.odp file.
Operating System: Linux (Other)
Version: 220.127.116.11 release
Confirm reproducible with LO 18.104.22.168 & displayed the same on PPV 14 (Win7 32bit).
Looks like text box setting broken after filesave in PPTX.
the overlapping is due to the fact you have 3 text boxes with text arranged in multuple lines.
however when you save in .PPTX, the text of each box is saved in a single line that goes beyond the margin of the box, thus resulting in overlapping.
this is basically Bug 71961
FILESAVE: text doesn't fit into text boxes after saving as .PPTX
