Public bug reported:

When copying a large amount of data (50+mb) to a network share, my mouse pointer slows to the point of uselessness. All other PC functionality seems normal. Interface with apps via keyboard / Alt - Tab , etc works fine. The only symptom is the lack of response from the mouse.
>I am copying to the net share over a WIFI connection.
>Copying data via wired ethernet connection exhibits no problems.
>My mouse is a Logitech bluetooth mouse.
>Laptop is a Dell Latitude E5520 with stock Dell Bluetooth interface. (Dell Wireless 375 Bluetooth Module)
>OS is Ubuntu 12.04.01, 32bit.
>CPU History in System Monitor shows nothing out of the ordinary. Processors utilization is very low. Network History in System Monitor shows heavy load.
>Normal day to day operation is outstanding, but I don't know where to turn to find the cause of this problem.
>Have been using NetHogs 0.8.0 to observe detailed network traffic. This problem only occurs during large file transfers using Wifi.
>Symptoms seem similar to bug #334549 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/334957)

Any and all help appreciated!
