Asset warp tool on a layer

You create a character of a layer or more layer. I did create a character of more layers. When i put warp handles on them, the stage objects don't glitch. I deform them and the stage objects don't move as when you deform a stage object. The best way to create animation with asset warp tool is how you deform a stage object. I put together the layers, the character is created of to a layer. When i put warp handles on a layer, parts of a stage object's fill become invisible. Asset warp tool is how i got to create animation. But does it always screw up, i am not going to.

Hello, could you kindly elaborate a bit more? What is glitching? The layer? The drawing? The warping? How does the glitch look exactly? Please provide a screen recording showing the issue.
