Starting last night during the airing of Prodigal Son an image of the Roku remote and the OK button started appearing on the left side of my screen (TCL 2017 55” roku tv). Clicking the OK button did precisely nothing. I am clearly not the only person as evidenced by a topic on Reddit in /r/roku.
Is this a feature that is being developed? Something that went wrong in a firmware update?
No the image isn't persistent, but it returns within a varying timeframe of every 30 to 120 seconds. It will stay up for about 20 to 40 seconds. Then return.
It does seem from the thread on reddit (which I also referenced in my PM) that most observed this first during the airing of the tv show Prodigal Son on FOX. It kept reappearing afterwards too though during all other programming.
