Issue
The issue I'm noticing began occurring after 1.63 came out. Whenever you are moving your mouse about in your inventory, some of the inventory slots begin turning red. It happens with just my inventory, as well as when I'm in my AE system. Isn't a system breaker but semi-annoying visual glitch.

If this is a feature request, feel free to delete the template.
