It seems like when the panel updates the image, the entire panel “flickers”. The url it is loading every couple of seconds:
http://homeassistant:8123/api/media_player_proxy/media_player.emby_kodi_livingroom?token=1867541008&cache=e94b9
If the image isn’t changing, maybe it should send a not modified response and not flicker the panel? Or maybe it is the progress indicator rendered on top of the image and that is why the entire image is reloaded? Either way, the flicker is…distracting
