It's not a bug - when you uncheck that setting, all affected particles are converted into unique meshes, in order to properly orient their mesh to match your Rotation settings. In other words, when you disable that setting, instancing is no longer possible...this will cause slowdowns if you have a lot of particles.
Oh, I see. Thank you for your explanation
There is a problem, as in the case study. I want to make the direction of the grass more random, so I must use "Random horizontal". At this point, I need to create a rotation animation for the particles based on the "world X-axis direction". At this point, the rotation is "local coordinates". This is why I want to cancel this option. Is there a way to reset the coordinates of the particles? What I mean is to keep the previously chaotic coordinates unified again. Of course, the shape and direction of the particles cannot be changed. Can this be achieved?
If you don't understand what I mean, please take a look at the picture
