I started to do some third party testing and one of my testers is reporting weird colour glitches. Disabling particle emitters fixes it. Any ideas what might be causing this? Can I fix this somehow on my end?

Does the particle system has special requirements? Anything the user could install to make this work?
I would recommend to update drivers, but the particles have been giving problems for a while, it looks like when I started with OpenGL and broke it in crazy ways, because forgot to initialize this, enable that, or tried wrong texture/viewport/object coordinates 
Maybe there is a little bug in the (new?) particles system 
Well, ok I can recommend my users to update their drivers… Would still be great if you guys can make sure that this isn’t an in-engine bug though.
