@popcornmix found the cause. The still frame issue only happens with the two "mmal advanced" deinterlacers and not with the "mmal bob" ones or with deinterlacing disabled. So it's not a generic Kodi sw rendereing issue but somehow related to these two deinterlacers. As already mentioned, it's not a show stopper issue and probably not worth further investigation, but if you are bored/curious and want me to test a possible fix, let me know.
