True Colors - S1-E6
Continuity mistake: Walter and Paige begin dancing and there is a lady dancing in a green dress behind them. In the next frame, that same couple is dancing across the room and then a second later next to Walter and Paige again. Walter's left hand holding Paige's in a dancing position also changes from open to closed. (00:26:05)
Factual error: In the scene, Floki walks towards a small waterfall today known as Kvernufoss. Floki is supposed to be the only inhabitant if not the entire Iceland, at least the region, as we are shown no sign of civilisation whatsoever, and as historical record tell us about Iceland in the early 800s (as the events of Vikings seem to take place). But a well beaten footpath is visible, leading to the waterfall at the end of the canyon. That path is an oft-travelled path tourists follow nowadays to reach Kvernufoss, a well-known site in the area. A path like that in Floki's time would simply not have existed (there is nothing in that canyon but that waterfall, no reason to go there if not for sightseeing) and represents a (tiny) intrusion of our modern world in a show set in the middle age Iceland.

Partners in Danger Chapter 6: The Awakening - S4-E6
Continuity mistake: When Morbius is battling Spider-Man and Black Cat on the rooftop, his red eyes are colored white in a couple of shots.
Tsuinzu gâdo - S1-E5
Other mistake: Van transfers the bunch of condiments from the cart to the table. Amongst said condiments, a big jar of "MASTARD." (00:07:00)
Beyond the Farthest Star - S1-E1
Other mistake: When showing Scotty on the bridge, some of the frames show more of his body than others. In those frames, you can see that he lacks legs.
Continuity mistake: When Silver Surfer is engulfed by the Fractite, he is standing on the middle of his board with his left foot closest to the front (the "goofy" stance), knees slightly bent and arms extended to his side with his elbows slightly bent. In the next scene, he is shown to have both of his feet pointed towards the front of his board, with his knees bent more and his torso leaning back. The Fractite holds him in place, similar to if you were frozen in ice, so he wouldn't have been able to freely move.
Visible crew/equipment: At the end, when Aunt Vi and Delilah return home, just as Miles walks into the house, the green T-mark is visible on the floor.
Shelter from the Storm - S3-E18
Continuity mistake: When Winn and Brainy hug, Winn starts the hug with one arm high and one lower, towards Brainy's waist. The shot cuts and both his arms are up and in the centre of his body.
Beauty and the Obese: Part 1 - S1-E1
Continuity mistake: At the bar, a man slides up behind Persephone and asks how much for a lap dance. It cuts to a different angle as the bar tender comes up, and suddenly the bottles on the shelves behind the man have changed around. Most notably the orange bottle on the second shelf. (00:02:30)
Character mistake: There is a spelling error in the newspaper that Sakurako Sawatari is reading in one episode: the word, "admits" is spelled "adwits." (00:01:00)
Visible crew/equipment: During the final battle between Duncan and Luther, you can see a crew member holding a boom microphone pole standing on the stack of hay bales in one of the shots. (00:44:10)
