--- Comment #6 from James Moe <jimoe at sohnen-moe.com> ---
linux 3.11.10-7-desktop x86_64
gnome 3.10.2
Gallium 0.4 on NVC1

This issue has surfaced again in a slightly different form recently, within the
last two weeks.

The mouse data stream is interrupted and restarted at random intervals, in
generally less than a minute. By "interrupted" I mean that the current mouse
state is cleared; if button1 is down, it appears no longer down. And
"restarted" means that the mouse state is restored immediately after it is
interrupted but it appears as a new state: button1 is now down.

It makes button1 click-drag a chancy process as the stream is sometimes
interrupted/restarted quickly enough that it appears as a double-click followed
by click-drag.

Still using a kernel "tainted" by VirtualBox.

This new aspect has no obvious affect on CPU usage.
