Short description of error
Only one hair strand visible in OpenGL and Eevee views when using child hairs (affects both simple and interpolated) when the display amount goes above a 16 in my case. This is for strand hair shape type. However when the strand hair type is set to strip, the problem occurs when the display amount is over 8. The render amount in Eevee seems to be affected as well when I hit the render button. This does not affect Cycles rendering.

display amount set to 16
display amount set to 17

Exact steps for others to reproduce the error
In a new blend file, simply add a particle system to the default cube and set the emitter type to hair. Then scroll down to the children panel and select either simple or interpolated, and then increase the display amount until all the hairs disappear and you're left with one strand. Then try decreasing the amount until they all show up again, and then in the render settings, change the hair shape type to strip and they all disappear except one.
