As of [0.20.0](https://github.com/liabru/matter-js/pull/1300) there is now built in `Matter.Runner` support by default for fixed timestep with high refresh displays see https://github.com/liabru/matter-js/pull/1300. Therefore hopefully this will now be much easier. Thanks...

Thanks for sharing, helpful for multiplayer games especially. Another browser consistency issue can sometimes be seen in the native array sort implementation ([sort stability](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#sort_stability)). It feels like there would be...

Thanks for sharing this test case. It looks like moving [L38-L42](https://github.com/liabru/matter-js/blob/master/src/core/Sleeping.js#L38-L42) to come after [L48](https://github.com/liabru/matter-js/blob/master/src/core/Sleeping.js#L48) in [Matter.Sleeping](https://github.com/liabru/matter-js/blob/master/src/core/Sleeping.js) might be what's needed here - is that what you tried out?

That's right currently for performance and simplicity reasons only the parent body `collisionFilter` is used rather than from each part, so I think you might need to use constraints to...

Could you try this [alpha build](https://github.com/liabru/matter-js/tree/fix/sleeping-collision-end/build) from PR #1079 and let me know if that solves the issue? Otherwise if you're able to share a minimal example that would help!

I think poly-decomp might only support "simple" (non-self intersecting) polygons without holes - could that be part of the issue? If you need something like that you may need to...

Could you share an example of the issue and explain further?

I think in principle that seems like it might work, though as it stands I think `Query.ray` intentionally does not return individual parts (only the parent). So you could try...

See #659

Hmm, well `Bodies.fromVertices` is supposed to handle this already. Strange that it isn't working for this case though, I will need to check this out a little closer when I...
