Re: firefox slow,jerky scrolling and misaligned pages while scrolling. Gnome3+Debian
You're probably right, fiddling with PowerMizer does not solve the original issue, it just mitigates its effects be increasing GPU computational power.
I don't think that it's a Window Manager problem, as it can be reproduced with gdm, kdm, xfwm4 and probably a bunch of others. I assume it's either Xorg <-> nvidia or kernel 3 <-> nvdida.
