Hello!
I couldn't reproduce with the following steps:

  • Open default blend file.
  • Add a modifier to the cube of type Particle System.
  • On the Particles tab, switch from Emitter to Hair.
  • In the Viewport, switch from Object to Particle Edit Mode.
  • No crash!

Can you confirm that with these steps Blender crashes for you? If so, please try also with the very latest Beta build.

I've the same issue on this version :
Version 2.80 Beta
Date : 2019-01-04
Hash : 2c21e3e35f30

With Macbook Pro on MacOS High Sierra (Version 10.13.6)
Graphic Cards : NVIDIA GeForce GT 650M 1024 Mo and Intel HD Graphics 4000 1536 Mo

I also tried with default blend file with a cube and a particle system and same issue.
Cannot use comb.

I also have some weird behaviors on the viewport. Hairs particles does not displayed correctly on the viewport (Solid mode not render mode), when Eevee is set as the main render mode. If I switch the render mode to Cycle and I undisplay and display again the particle system it works. This issue appears on the Solid mode and the LookDev mode.

@Camille (Ekiwnox) you confirm that you get a crash from the default file with these exact steps:

  1. Open default blend file (cube is selected).
  2. On the Particles tab: click 'New' and switch from Emitter to Hair.
  3. In the Viewport, switch from Object to Particle Edit Mode. does it crash here?
  4. Comb the particles. or here?

I still can not reproduce as of today on Linux, but with 2 similar reports from macOS, it could be something platform dependent.

Yes I confirm I get the crash with all these steps, as you can see on the video bellow.
You can also see how wrong the particles systems is displayed during the first step.
Hope it will help you :-)

hi,
exactly same story with two releases Dec.3 and todays download from Jan.05.

macOS High Sierra 10.13.4
Nvidia GTX1050Ti 4Gb

This is still happening with version 2019-01-08

Can also reproduce this bug following the above steps using the latest build (3c3d80ea22af). The crash occurs as soon as particle edit mode is selected from the drop-down menu.

Mac OS 10.11.6
NVIDIA GeForce GTX 670 4095 MB

I figured out that you can enter particle edit when the object is not visible in the viewport and then already in p.edit mode turning the visibility on.

I'm not sure how you accomplished that, since Blender won't allow me to enter particle edit mode with the object visibility turned off.

However, that just led me to discover that if you set either the "rendered display" or "viewport display" in the particle system settings to "none", you can then enter particle edit mode and edit to your heart's content. If you change the viewport display setting to path while in particle edit mode, Blender crashes (see: https://developer.blender.org/T58233), though that bug seems to be not GPU specific.

Same issue here on macos.
blender v. 2019-01-16
