Continuity: In the Season 7 episode "Cure", In the scene where Clark and Knox fight, Knox smashes his blue container with his weapon. Shortly after this, there is a shot where he is looking in horror at what he'd done and behind him, Chloe is struggling with her ankle cuffs. She appears to be wearing shoes in this frame, where-as before and after, she is barefoot.

Audio problem: When Clark and Manhunter are in his Barn talking about how to stop Bizarro and figuring out the yellow sun can heal Clark, there is a beep of a watch or someting similar in the background, but neither Clark nor the Manhunter react to it, which means it happened off screen and unintentionally.
