Ah, thanks that is important info. In that case I think what you are seeing
is electronic interference from the webcam. I have that exact same mode,
and I opened it up once, there are 2 crystals in there for high frequency
clocks in about the same frequency as the radio frequency used by some wireless
devices, and all the electronics in the webcam are completely unshielded (as they
are in most webcams).

So I think your options are limited to:
1 do not use a wireless mouse
2 get one of those new wireless mouses which use one of the Gigahertz bands to
   communicate
3 get a new webcam

Regards,

Hans
