Particle System Issue - Texture stretched to fullscreen

[MoserAlex]

Hey hey

We have encountered some weird behaviour in the particle systems we usually set up. When playing a particle system, which uses a texture for its particles, in the first frame of playing it, the texture is scaled up to span across the whole screen. It looks like a short flickering, after which the particle system behaves normal. It also only happens the first time the particle system is played. If we stop and reset it, the next time we play it it’s fine.

To reproduce this issue we had to:

• Set up a particle system component
• Set the autoplay flag to true
• Set the sort order to anything other than NONE
• Add a texture asset as the color map
• Set the preload flag of the texture asset to false
• Set a timeout to 0 seconds, when the particle system is paused

You will see that the particles are huge. I set up a reproduction project and posted about it in the forum.
