The line is a shadow on the image, in PowerPoint it can't be seen (probably because it's configured that way), but in Impress it's shown. The change could be bisected to the following using repo bibisect-43all (it was already buggy in oldest commit of bibisect-41max): https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=9351d0e4181924c3f72be24081fc7af027aa41f7..fba5febdf60b37be69d2ffc66445d3e324826346 Found two commits in the range that deal with import of shadows on objects: https://cgit.freedesktop.org/libreoffice/core/commit/?id=f0efecfb69b336e064e7c8dd2597655eff07944f https://cgit.freedesktop.org/libreoffice/core/commit/?id=e1a509f4a362d21248b439c99e3b55f4fa9ba1bd All in all, it seems like an implementation error rather than a regression, it's just previously the shadow wasn't imported at all (when making the shadow visible in PP, it still can't be seen when imported in an older LO version).
