FLIP Fluids Addon: A liquid fluid simulation tool for Blender

Ahh, that’s too bad. I am curious, does setting the render display to ‘Full Screen’ help?

full_screen

I just read a tip that this can help for unstable animation renders.

This is not supported at the moment. We are in early development of a feature for mixing different fluids (variable viscosity), and do plan to start experimenting with mixed-material fluids afterwards. Since this is still an experimentation and work in progress, we do not yet have a timeline for when this will be added.
