Blender Version
Broken: version: 2.83 (sub 13), branch: master, commit date: 2020-04-09 10:35, hash: rBa6d8f6c0f30

Short description of error
Particle Hair cannot be selected anymore

Exact steps for others to reproduce the error

particle_hair_select.blend560 KBDownload

  • open blend file (or just create a hair particle system on the default cube)
  • try to select the emitter object by clicking on the hair (or using any other selection tools e.g. Box)

Apparently caused by rB3685347b4172: Selection: Add conservative rasterization to select really small objects
Displaying hair as thick strips doesnt seem to help here

(noticed this while looking into new Hair object selection - a pending TODO in T68981: New hair object type)

@Clément Foucault (fclem): I tried this with the hair-non-transform-feedback workaround, but that also fails, got an idea?
