Hello Luigi,
By default images are inverted in dark theme. For most of images it is describable strategy, that sometimes might cause problems. However, in image editor you might specify which images should be converted automatically, and which doesn't. Just double click on image and you will see the dialog. In this dialog you can set "Fixed colors".
For more information about dark theme support, please read following documentation page.
