I vaguely remember spotting some sleeve problems in toy story, but can’t remember where off hand. It may be during the ‘strange’ things montage with Andy’s shirt but I’m a bit fuzzy.
Maybe they animated that stuff too fast or something.
I have a feeling it has something to do with the vest she’s wearing, somehow that threw off the sim for a brief moment.
I noticed yet another error:

At 1:41 when Woody flies up into the air, the shadow of the kite abruptly jumps, I guess because the animator immediately moved it over to its position for the next time it appears in the shot. It’s still there in the final film too.
I never noticed the one Kyle showed us after a few times but i never noticed that in the theaters. 
That’s one I didn’t notice. My guess is they needed the kite to go a certain distance in a short amount of time, so once it got of frame they figured they could have it jump instantly forgetting about the consequences of the shadow since they don’t see those while animating. .
I didn’t notice that one either but i played the part a lot of times and I still can’t see it. I did see the one with the bed post in the wall. Good find Kyle. 
You still can’t see it? its pretty obvious once you know where to look.
Okay, I’ll try again
I never noticed that one either he,he.
