Question Having issues with Tilemap Collider + Composite Collider

Apologies if this is a beginner's issue, I just started out with Unity a couple of weeks ago.

I keep having problems with player movement whenever I use the Tilemap Collider. The problem is that whenever the character moves to the right on the tilemap tiles, it is as if the player is constantly colliding with the tiles that I placed on the grid, causing a stuttering / jittering effect. This is probably due to the player jumping between different animations (my guess is that it switches between the walking and falling animation). The effect is quite subtle in the clip, but in my editor it basically looks as if the player is having a seizure.

A couple of things to note are that this only occurs when the player moves to the right on tilemap tiles and the issue does not occur on "plain" game objects such as 2D squares (white platform above).

Some things I've tried with no avail:
- Replacing the player's box collider with a capsule collider (same result with a polygon collider).
- Working with the standard tilemap collider without the composite collider. While this removed the jittering, it seemed to create spontaneous "invisible walls" that the player occasionally got stuck on (appeared infrequently, sometimes at the same spots, sometimes at different spots).

The only workaround I have for the moment is to apply a box collider manually to the entire row of tiles. While I'm happy that it resolves the issue, it's not an optimal solution in the long run. Am I missing something obvious here?

P.S. The player's rigidbody settings are set to Continous Collision Detection and Interpolate.

 

Thank you so much for your quick reply and tips. I'll try it out!
