Public bug reported:
Whenever my PC has a lot of network IO (e.g. when downloading something from
the web, copying backups over ssh, ...) the mouse pointer becomes extremely
slow and trails behind up to three or more seconds. Yet, most of my movements
are buffered, so they still happen, but only with a delay.
At the same time, everything else, including keyboard, audio, and even resource
intensive tasks like 3D graphics, is still handled quickly and is perfectly
responsive.
This happens so often that even every day tasks become difficult to
accomplish. The PC has brand new hardware (Core 2 Duo 6600, Gigabit
Ethernet, etc.) and should definitely be fast enough to handle all tasks
at once.
