Thanks for your testing, to answer your questions: - the file was NOT created or ever manipulated in a pptx format. - The fonts used are the most common on earth: Arial and Liberation (the latter I think installed by libreoffice itself). But there is more: inspired by your questions, I saved the file in PPTX format (using Libreofice to save in pptx) and got two interesting results when reopening (in Libreoffice 24.8) the file converted into pptx : 1 - the text objects are NOT corrupted if I display the slides full screen; 2 - the BAD news: ALL the math equations are LOST, you don't see them and they are not there even as invisible objects! This is another (grave) matter, so I think I will file a separate bug. Notice also that: - I have installed on the same PC both 24.2.6.2 AND 24.8.2 (via Reisisoft that allows to make multiple installs of different versions) - The pptx converted version (it does not matter if it is converted with 24.2 or 24.8) will NOT display all the math equations when opened with 24.8, while it does show them if opened with 24.2 - if I convert back the pptx version to ODP, and open it with 24.8, the display corruption is not there anymore; of course there are a lot of small formatting differences that needs to be ironed out, but the passage through pptx seems to have eliminated the source of text objects full screen corruption. HOWEVER, I cannot apply this treatment to eliminate the full screen corruption: I could tolerate the work needed to solve the glitches in formatting involved by the passage back and forth through pptx; but the problem is that all math equation would be LOST!!! I am sorry, I understand that things are complicated, but... I hope to have explained them understandably. last note: all math equations are lost when reopening the pptx-converted files with 24.8 not only with my attached file but with ANY IMPRESS FILE!!! This does NOT happen with 24.2 -- You are receiving this mail because: You are the assignee for the bug.
