Package: iceweasel
Version: 3.6.16-1
Severity: normal
1. Go to http://members.dslextreme.com/users/billw/gkrellm/gkrellm.html
2. Press Ctrl+A to select the page (the page is broken and unreadable
without this).
3. Drag the page content and then release the moues button.
Now a smaller version of the page content appears offset by the drag
slowly returning back where the drag started consuming horrendous amount
of CPU time.
The smaller version of page content is also visible at other pages but
on this one Iceweasel is substantially slowed down by rendering it.
