Short description of error
Eevee rendering with F12 using the Hair particle system. Instead of single hair strands it creates rectangles center on the middle of the object. Eevee viewport render looks fine and also Cycles.

Just to confirm the above and add the same result happens for workbench render.

Just chiming in to say I've encountered what I assume is the same bug. My specs:

Seems to effect workbench as well.
Would assume that the draw cache for rendered strands adds an extra position that is set to 0, 0, 0

Hi.
Here a user reported a problem that is currently solved in the latest version of master that I have compiled:
https://blenderartists.org/t/blender-2-8-eevee-hair-discrepancy-between-viewport-and-render/
I am not sure that it is the same problem as reported here because Strand method is used here and in the problem of the forum is used Strip with Children. Commenting here just in case to know if you are aware that this or another commit could have fixed this problem as well.
