Operating system: Linux-4.15.0-66-generic-x86_64-with-Ubuntu-18.04-bionic 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.26
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-11-08 22:59, hash: rB0a0d735acd6e
Worked: version: 2.80 downloaded from blender.org (blender-2.80-linux-glibc217-x86_64.tar.bz2)
Short description of error
For an emitter particle system, Viewport Display -> Display As -> Circle/Cross/Axis show only first two particles (see screenshot). This seems partially GPU/driver-dependent, as I've been able to duplicate with two separate Nvidia video cards (using both a very old and a brand new version of the proprietary driver, as described below), but the bug is not reproducible on my laptop w/ integrated Intel graphics using the same Blender version.
Specifically, I've duplicated this problem with the above Blender 2.8.1 version (beta download from blender.org in blender-2.81-0a0d735acd6e-linux-glibc217-x86_64.tar.bz2) on:
Machine #1: Ubuntu 18.04 w/ GTX 1080 using Nvidia driver version 440.26 Machine #2: Mint 19 w/ GTX 760 using Nvidia driver version 390.116
I've also verified that the Blender 2.8.2 alpha version and a version built from a recent Git pull exhibit the problem, but the stable 2.80 version (blender-2.80-linux-glibc217-x86_64.tar.bz2) works fine.
Exact steps for others to reproduce the error
- File -> New -> General
- Select default cube
- Add a particle system
- Start animation -- particle system is displayed in viewport.
- Switch Particle Properties -> Viewport Display -> Display As from "Rendered" to any of Circle/Cross/Axis. Particles disappear, and when animation restarts from frame 1, only first two particles are shown.
- Switch Display As back to "Rendered" or "Point", and normal particle system display reappears
