[Bullet] move_and_slide_with_snap causes erroneous movement near edges

[jackwilsdon]

Godot version: v3.1.stable.official

OS/device including version: Windows 10

Issue description: move_and_slide_with_snap causes a KinematicBody to slide of it's own accord if it's near an edge.

Dropped directly on the seam

Dropped near the seam

Note that this doesn't happen when dropped near the seam if the static body on the left is not present.

Steps to reproduce: Create two static bodies with box collision shapes that are touching and drop a KinematicBody using move_and_slide_with_snap near the seam (doesn't happen with move_and_slide at all).

Minimal reproduction project: seam_bug.zip

happens with move_and_slide() and move_and_collide() in 3.1.1

Related to #28438?

[jackwilsdon]

@madmiraal #28438 doesn't seem to be using move_and_slide_with_snap, although I guess that doesn't eliminate the possibility of them being caused by the same root issue.

Still valid in 3.2.4 beta4

[pouleyKetchoupp]

Can be still reproduced in 3.2.4 beta 5, but occurs only when using Bullet Physics (default settings). Switching to Godot Physics 3D fixes the issue.

[David-Ochoa]

Well, it doesn't fix the issue because I can't switch from bullet to godot Physics, it's more accurate to say it's not present on Godot Physics

[pseidemann]

I confirm this issue still exists with move_and_slide, v3.4.4.stable.official [419e713], macOS 12.3.1 (21E258) with the Bullet engine.
In my case I just walk over the seams which causes my player to make little jitter jumps which disrupt the experience.
