Hi @Mitze23838,
Greetings from the Roku Community!
Thanks for reaching out. Could you tell us how long you've been using this device and when did you start seeing this behavior occur? Have you tried using this device on a different TV, and does seeing the same issue? Also, does a simple restart help relieve the issue, or does it come back even after the troubleshooting?
Let us know more about this so that we can further assist you.
Thanks,
Rey
