Warp is a very complex, very high-computation effect. I think easily the most CPU-demanding effect in the app. And it has quite a few options in its presence in the Effects Control Panel.
The default "Result" option is Smooth motion, where it simply tries to cut down jumpiness. The other option there is no motion. Typically smooth motion is better, but you can easily go to the Smoothness control number block, click/slide left to right, to change the 'smoothness' to more or less.
You can go below it to set the "method", and other options. It's complex, complicated, and you'd do good to look it up in the Help files, the Premiere Pro User Guide Online , and in say LinkedIn Learning video series on working with Premiere Pro. I don't have any YouTube's I currently like for this, and several of the ones I've watched I would never recommend following.
