Artifacts when HW decoder is used for SD h264 content

Full debug log

With HW decoding enabled showing artifacts and SW decoding enabled working as expected.

Had to take a picture of the TV as taking a screenshot in Kodi don’t show the artifacts.

While I don’t think it’s at all likely to be the cause of your immediate problem, this is an odd combination:

Force RGB output: false
Use limited colour range (16-235): false

Normally if the output is not RGB you would expect it to be “limited” rather than “full”.

This is a known bug. You can avoid it by trying different zoom settings. Or else…

Hopefully the issue is now addressed:

I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:

  1. Login via the command line
  2. Run the following command to add the staging repository:
    echo 'deb bullseye-devel main' | sudo tee /etc/apt/sources.list.d/osmc-devel.list
  3. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  4. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you remove /etc/apt/sources.list.d/osmc-devel.list after updating.

This will deactivate the staging repository. You can do so with the following command:
sudo rm /etc/apt/sources.list.d/osmc-devel.list.

Please note that we will automatically disable this update channel after 14 days on your device in case you forget to do so to ensure that your system reverts to the stable update channel.


  1. I can confirm that the issue is Zoom related
  2. Updating to staging repo solves the issue
