Pausing live tv freezes video

…if show ends while paused (even for just a few minutes) and then I resume and ff through commercials. This seems to only happen when using chrome on a pc and usually after I overshoot the ff and rewind a couple of clicks. Is this SOP or something else? Maybe it’ll become a moot issue once the auto commercial skip is implemented but it’s a drag when pausing live tv is a major draw for me. FWIW, this is with a dual tuner box and nothing else scheduled to record or any recently ended recordings generating thumbs. Thanks for any insight you folks can offer.

What playback device?

Chrome on PC
