Hi Mikejapan
Thanks for the post.
Does the issue occur on your Roku home screen or does it start when you launch a channel? What's the model number of your device? It can be found in Settings > System > About. With more information, we can assist you further.
All the best,
Kariza

Hello rdilloway8
Thanks for reaching out here in the Community.
Could you tell us how are you powering your Roku stick? Is it connected to the USB port of the TV or to a wall outlet? In some cases, the USB power provided by the TV is not sufficient to power the device. Even though your Roku device may appear to be working, running with insufficient power can lead to instability, crashing, and other unpredictable behavior.
Using the included power cord and power adapter, we suggest plugging your Roku into a working power outlet in the wall. Powering it through a power outlet in the wall has the additional advantage that your Roku player will not need to power up every time you turn on your TV. This means your Roku player will be up and running faster than it would be connected to a TV.
Let us know if there's any difference after.
All the best,

It is plugged into a surge protector strip outlet, not TV.

rdilloway8 What size is your TV? When you setup your Roku it finds the optimal size for your TV. Did you do that? If not you can redo it.
- Press the Home button on the remote to access the Roku home screen.
