Hello,
I have the latest version (from 2019-04-15) installed and I'm trying to use Presentation for the first time. I have a very annoying bug: embedded pictures are not shown from the second time you open the file onwards. I explain: I prepare a presentation, I include a picture and that gets displayed fine. I save the file and close Presentation. When I open the file again, the image is not shown on the slide. The image is still there (if I click on where it is I select it and I can operate on it), but a white box is shown instead of the image. I have WPS installed on Debian testing, the problem is there both in KDE and Gnome.
Kind regards,
Iacopo
