Some problems with Grit Grinder's visual effect

It seems that Grit Grinder's salt covering visual effect relates to which part of a turf you step in first. This cause at least 2 visual problems.

1 Salt floating in the air, caused by stepping in the edge of the turf, like the red circle

2 Unnatural connection of salt covering ice turf, like the purple circle(I just mark one because there are too many). This connection results different problems. For example you can see in some areas salt grain is very dense, and some areas are not covered with salt at all. Though I make sure every turf is affected by Grit Grinder.
