The mouse is not really related : it just
make the problem easier to happen... it's
actualy when you scroll down quickly a page.

Note that it's not related to the browser,
content of the page or even software (you can
do that in other programs too). It's a problem
with the graphic card and its drivers.
Perhaps try to upgrade the driver to the latest
version...
