Hi @Macadamius,
A warm welcome to the Roku Community!
Would you mind providing us with more information regarding the issue you are experiencing? Does the issue only occur on a specific channel or all the channels installed on your Roku device? What troubleshooting steps have you taken so far to try to resolve the issue? Have you tried connecting the device to another HDMI port as well as using another HDMI cable to see if the issue persists? In addition, have you tried connecting the Roku device to a different TV to see if the problem occurs there as well?
Please keep us posted, and we'll continue assisting you from there.
All the best,
Chel
