Short description of error
It seems that a geometry node scattering system created on one object can somehow change the display color of other point-cloud type objects, see gif

If we change the density of a scatter system assigned to this blue object, it can somehow change the display color of the other scatter object with a point cloud type

Exact steps for others to reproduce the error
In file below, enable the node

Do you think this node setup (and geometry too) could be simplified? I can reproduce the issue, but I have no idea what is going on in this file.

@HooglyBoogly Can you check this?

I'm also having trouble understanding the situation, since the file is quite complex-- I'm not sure that there isn't other things changing besides the number of points.

@BD3D, would you be able so remove the unrelated nodes from the node tree while keeping the issue intact? That would help a lot for narrowing down the problem.

That's as much as I could clean up this file. I don't have time to understand if there is a bug or not so will leave it to others (or other time).

I can reproduce this with a much simpler setup. Looks like over 2047 instances can change the point cloud's object color. The issue still happens with -t 1.
