Different rendering of odg document between mac and linux

Dear all,
I have different .odg files created under linux (ubuntu), where I inserted some pictures that I cropped and resized. Unfortunately, when I open the odg file in mac osx (I tried with High Sierra and Catalina, and LO versions 6.3.6, 6.4.5 and 7.0.0) the rendering of the images is totally wrong. Attached are the screenshot of the images in the files opened in ubuntu and in macosx.
