Hi,
I am using now LibreOffice 5.2. I have the presantation made in this version of Impress or maybe even in earlier version. After upgrading to version 5.3 the layout of text in the slides have changed. The problem exists in the version 6.0 too. It is visible on the attaches files:
Screen from LibreOffice 5.2:
Screen from LibreOffice 6.0:
It is not the problem of Windows 10. I've made a second screenshot on Windows 10 with newly installed LO 6.0, but some time ago I've upgraded LO from 5.2 to 5.3 on Windows 7. When I saw that slides do not look like expected then I made a downgrade to 5.2 and everything returned to normal.
Is it a bug in new LO? Maybe some default setting has changed?
Cheers,
Marcin
