Hi, @Marshastetler.
Welcome to the Roku Community!
Thanks for sharing your experience here with the issue you're having with your Firestick connected to your Roku TV. we'd like to help you sort this out.
Have you tried inserting your Firestick into a different HDMI port on the TV? If not, we recommend doing so to see if there are any differences.
Also, is this happening on a specific app or on all apps inside the device? If so, have you tried streaming using the apps on the Roku Home Menu to see if the issue persists?
Let us know what you find out.
Best,
Emman
