text wrapped after saving as .pptx

the test file you uploaded is not a .pptx but rather a .ppt and looks OK in Win7x64 using LO

however if I save it to .pptx, close and reload it, then the text gets wrapped and a bullet is added (see screenshot)

so I change status, summary notes and platform.
Comment 4 Ofir 2014-05-01 08:01:59 UTC
You are right. The problematic file is PPT and not PPTX but the PPT has a problem on Ubuntu 14.04.

Can you please verify that the text wraps in Ubuntu 14.04 with the original PPT and change the title and file name to match the issue?

sorry I don't have Linux machine to test.

according to what you say and my tests the bug is present in .ppt format under Linux and only after saving to .pptx under Windows

changed summary notes to better reflect this situation.

Reproducible with LO, Ubuntu 14.04.

After installing the ttf-mscorefonts-installer package, the text is OK and doesn't wrap. So is it a font substitution issue?

Saving the ppt to pptx, the font changes from Arial to Dejavu Sans (select text - Format - Character: CTL font). This causes the wrapping.

In 3.3.0 the font does not change, but the change is already in oldest commit of Linux 43all repo

Does this only happen with RTL content? Can we reproduce it with LTR-only?
