Issue description

When sliding CharacterBody3D with capsule collision shape around StaticBody3D with cylindrical collision shape, CharacterBody3D movement is choppy, moving back and forth randomly.

Steps to reproduce

Run sample project and slide the ship with arrow keys around the island.

I'm seeing very similar behaviour in a new project, also Godot 4, beta 2. I have a CharacterBody3D with a capsule mesh + collider, sitting on a SphereMesh.

The snappy behaviour for me occurs right at the pole of the sphere, where all the edges meet. In the gif below you'll see me trying to move around smoothly, but struggling in that area around the pole:

For context, here is the mesh as seen in Godot's preview:

Likely related to the issue here - I have character body also with capsule collider, with gravity programmed in and jumping. And when jumping at colliders, it sometimes gets jitters, push backs, jump being blocked at beginning or even something that looks like teleports (seen at 4th second of the video below)

Same issue here -
The CharacterBody3D gets stuck and jitters around when colliding with edges

+1 to this issue. I've got a character body player that has lots of weird interactions when interacting with ConvexPolygonShape3Ds in my game. I've experienced this in every Godot 4 beta version that I've tried. (3, 8, 10, 12)

The capsule-cylinder collision from the minimal reproduction project in this issue is fixed in 4.0 beta 15. For the other cases reported in the comments here, please check again in the latest beta (since we've had more collision fixes merged recently), and create a new issue with a minimal reproduction project if the problem is still present.
