(at around 1h 11 mins) As Ed Hutcheson and Margaret Garrison are having a private talk, the glass in Margaret's hand switches back and forth between being held in both her hands or being held only by her right hand. Also, the amount of liquid in the glass changes from shot-to-shot.
When Hutcheson (Humphrey Bogart) lies down in his old bed, he remarks on the large picture of his wife's new beau, Lewis Schaefer (Phillip Terry) on the night table, very close to the phone. He then immediately falls asleep. In the early morning he is awakened by a phone call, and when he reaches over and picks up the phone, the photograph has vanished.
When Hutcherson is consulting with Margaret Garrison he is holding his drink with the left hand. However on the next immediate cut, the drink is now in his right hand.
The front page photo of the newspaper that Rienzi is reading is different from the photo taken at the actual scene.
Toward the end of the film during the court proceedings, the orientation of the court visitors as well as the set structure changes at various cuts. At one point two men are standing on the left-hand side of the court officer but in the close-up shots of Hutcherson, the men are not seen.
Also, when the two criminals enter, they are on the court officer's right-hand side. One sits down, and the other remains standing. However, during the long shots and other various angles, these criminals are not seen. Only when the proceedings end do you see them again as they leave.
Additionally, the structure of the court walls changes. A short distance from the officer's right-hand side, there is a short wall that then angles off. In various other shots, it is a long, straight wall. The same situation is on the officer's left-hand side.

The wall clock in Hutcherson's private office is missing a second hand.
(at around 25 mins) Ed Hutcheson, having just woken up, is on the phone and asks what time it is. The answer is 6:20, but the watch on his wrist appears to show about 4:45.
As Rienzi's car drives off after picking up Hutcheson, a large studio light is reflected against the side window of the car.
Ed Hutcheson's dictating headline calls for ten-point type, which would be about one-seventh of an inch high.
