heavy artefacts when switching channels in tvheadend

  • i moved my tvheadend from a burrowed raspi3 to a Intel N100 based system.

    i use a telestart digibit twin as an sat2ip device.

    I just moved the plugin folder from userdata addon_data to the new machine, both where tvheadend 4.3

    When i switch channels via the onscreen channellist or by up and down on the remote i get some flashing elements from the menu and after a second it switched,

    it is more disturbing when I ue the onscreen menu to switch.

    All that wasnt the case on the raspi3.

    Any ideas?
