Description Jun Nogata 2021-05-14 16:06:31 UTC
The default screen size for PowerPoint 2019/365 is "Widescreen". Widescreen is not screen 16:9. Impress does not have widescreen. Widescreen is necessary for interoperability.

Steps to Reproduce:
1. Open Microsoft Powerpoint 2019/365.
2. Click Design tab -> Slide Size, and select "Custom Slide Size".
3. Check the screen size "Widescreen".

    * Widescreen: 33.867cm x 19.05cm
    * On-screen Show(16:9): 25.4cm x 14.288cm

    !! Widescreen and On-screen Show(16:9) are different !!

    See https://support.microsoft.com/en-us/office/change-the-size-of-your-slides-040a811c-be43-40b9-8d04-0de5ed79987e

4. Open Impress.
5. Open Slides -> Slide Properties.
6. Make sure there is no Widescreen in the format.

    * Screen 16;9: 28.00cm x 15.75cm

Actual Results:
Impress doesn't have Widescreen, so when I open pptx, the Paper format is User.

Expected Results:
Paper size has a widescreen. Interoperability will be ensured.

Reproducible: Always

Yes in 7.1, but seems fixed, Widescreen is there now. I close.
