I have a problem with mobile devices when rendering moving points with outline post processing enabled. The points seem to get the outline as well at their center. I was able to reproduce this with a [fiddle](https://jsfiddle.net/3cjvx8fa/40/show) and the problem is only on mobile browsers. Desktop works fine. This problem can be seen by moving the view around a little bit (a yellow core shows up on some of the points).

Does anybody have a solution or a suggestion to exclude points particles from the outline pass? Or is this a bug?

This looks like a bug. Or maybe a limitation of the used approach (no point cloud support). I can reproduce the yellow dots even with an iMac. Do you mind reporting this issue at GitHub?

BTW: When using `EffectComposer`, don’t do this:

```javascript
renderer.render( scene, camera );
composer.render();

```

This will render your beauty pass twice. Just do:

```javascript
composer.render();

```
