CGI animation yeah...
More than half the characters of last generation games looked like eldrich abominations that clawed their way out of the uncanny valley. The games that looked "good" to me where the ones that went for their own look, so weren't trying to be cutting edge.
Considering pretty much all big budget movies lately are CGI heavy, it's even worse when they cut corners. Lots of animated TV shows do it to, or they just forget to add things in and hope no one will notice.
In Steven universe, I think it's Cheeseburger Backpack, toward the end when they're all in the water, his backpack actually disappears (you can't see the straps on his shoulders) and reappears half a second later, as if it were there the whole time.
In movies that have scenes with people eating, you might notice the food changes a lot throughout the course of the scene. (although in their defense, this isn't because of corner cutting or an "oops" moment, it's just caused by stopping and starting and stopping)
In Men in Black, when Will Smith throws the rock at the giant cockroach, it just kind of rolls off and completely disappears magically out of the scene, I think they were hoping the shadow would hide it, it didn't.
I also get to see every piece of product placement. Every major character uses a Macbook and you'll always see it from the back, so the apple is clearly displayed.
Except in the show Perception, Daniel Pierce uses a PC, always shown from the back, so the windows logo is clearly displayed (although this one I wonder if it's sincere product placement, or if they're just poking fun at Apple, or both.)
