[Bug 125970] Re: slow scroll with image in the background

[ligaard]

Could this be a GTK issue? I just observed that opening 'Gnome System
Monitor', then chosing it's 'Resources' tab (the one showing graphs of
load and memory usage) shoots X load to 50% (from 5-10%). At the same
time Firefox becomes very jerky, e.g. scrolling is jerky, typing in
textareas is jerky etc. Switching away from the 'Resources' tab in
'System Monitor' makes everything nice again.

I have a theory, that this could be a Cairo issue: Since the graphs in
the new 'System Monitor' uses Cairo. Opera does not use Cairo and it
works perfectly. It might be a driver/Cairo combination issue. I use the
Nvidia 'restricted' drivers.
