I wouldn't call this a bug - If you're making a 2D game then
viewplane alignment makes more sense, but for 3D particles you
usually want camera aligned billboards with full perspective
distortion. Here's a good illustrated article on the topic: <http://

That's how they're supposed to be. They're sprites, which should
always face the camera. Otherwise, at extreme angles (e.g. near the
edges of the screen), you can see that they're actually flat.
Best,
