Early and late game usually, I find that fast-moving ships tend to flicker in and out on the control panel (or whatever comes up when you press TAB) and it has a TON of beeping, espeically when there's a few talon wings or hounds going about.
Recreate: Find an early or late game save (doesn't have to be that, it's just easier to see what I mean) and get into a large battle with something that has a lot of fast-moving ships. Watch the control panel and you'll see that the first ships tend to flicker, and no orders can be given even though they are well within the detection radius, for a while at least.
I find this annoying because sometimes I waste CPs on a flickering hound or talon wing. I also find this problem quiet prominent with Pirhana Bomber Wings, even though they're slow.
