I’m experiencing the same exact issue described in your post using a Razer Mamba. Works perfectly fine in Windows 7, whereas on my primary Mac partition it jitters when moving diagonally, exactly as the video at the top demonstrates.

I’m running Snow Leopard 10.6.4 on a Mac Pro, early 2009 model.

It looks like a Blutooth adapter problem rather than what I described above. I’ve never had a single problem with a Magic Mouse myself (except of course awkward pointer reaction, which is typical for any mouse under OS X).

I had this jumpy mouse problem on and off with the Magic Mouse, and I finally took the time to diagnose it. It turns out that the bluetooth adapter flakes out and even turns off when it doesn’t get enough power, and it appears to pull it’s power from the USB bus (it may be USB internally; I don’t know.) I can reproduce this problem easily just by plugging in more and more USB devices, and the mouse will freak out and/or the bluetooth adapter will shut down (click on the bluetooth icon and it says “Bluetooth not available”).

Unplug your USB & firewire stuff (which is what caused the issue on my MBP), shut down the machine, let it rest for a few minutes, then power it back up.

Peace,

Cameron.

My Logitech Performance Mouse MX has had this issue for me as well

Thanks! I changed my Naga razer to the lower Hz setting and no more skipping!

What is “terrible”?

With me it’s the other way around. The Logitech G3 works like a breese, smooth just after I plugged it in my iMac, with Snow Leopard.
But it’s terrible on Vista (2 laptops) and Windows XP (1 laptop). Strangely it works nicely on one Vista Laptop..HP Pavilion AMD, with almost bare Vista on it.

I experience this with Logitech G5 on the latest Snow Leopard 10.6.4

It does not occur with my Logitech Corded Mouse M500. Unfortunately this mouse is starting to die, and requires a good thump on the desk every 20 minutes or so. :(
