Particles look different with orthographic camera on iOS

edit: apologies, the title is misleading - it actually has nothing to do with the camera being orthographic!

I’ve got a particle system that is supposed to look like this:

This problem does not come up when the player setting is set to desktop - only on iOS. What’s going on and how can I fix it?

Sorry to necro this post, but I am having the same problem. Does someone have a solution?

Could the texture be mipping to the extents of the borders? Try different mip settings?

Yep, it is possible this was the problem. Thank you very much!

Nice! Glad that it was something simple.
