Just got a new GPU (PowerColor RX 5700 XT) and using 2.81a was working on some bath bubbles so the file contains a Volume Scatter & Absorption Material and was also trying Particles.
The problem is the Viewport in Shading Tab I tried to preview render a small section of the particles not the material it crashes (monitor also goes off then back on).
It could be my GPU but after testing …
Tried re-creating just the Particles method in 2.8 & 2.81a which seems to work ok,
but when I try the material everything is ok until I add the Voronoi node. I tried Checker but works ok and tried a Voronoi texture for particle density but also works ok.
