I like KVM but after a month I noticed that switching inputs causes mouse and keyboard to stutter. After playing around with this, I found that it stops when I disconnect and reconnect my USB mouse and keyboard. I've tried this with many different keyboards and mice. I think it has something to do with all the devices being registered at the same time on the computer you're switching to. It's pretty annoying, but it still "works". Just not the way it should be.
