I have been using the open box window manager with Firefox (Debian
unstable with kernel 2.6.16 (preempt on)) on an AMD 3500+ & 2 gigabytes
of RAM. I also notice the same behavior. The video card is a 7900GTX
PCI-express with the latest NVIDIA driver , 1.0-8762 driver. The
problem was much worse with open source drivers and one of several (7500
AGP DVI, 9000 Pro DVI, 9250 DVI) ATI cards. Things seemed a little
better with the open nv driver, and slightly better still with the
nvidia driver.
An example of a website that gave me serious headaches was www.eham.net.
Painfully slow scrolling with the ATI cards. The CPU still gets pegged
at 100% with the nvidia driver, but scrolls much (click on the product
reviews link to bring your browser to a crawl) faster. Scrolling between
desktops in openbox, I can watch as the inside of the firefox window is
being redrawn; same for most GTK2 apps. Openbox draws the window
decorations instantly, so I doubt is a window manager issue.
The 7900GTX is driving a IBM l200p flat panel to 1600x1200 resolution.
The strange thing is, these apps are much snappier on my Thinkpad x41
with integrated Intel grpahics and a 1024x768 LCD. The eHam website was
never much of a problem as far as scrolling. So I wonder if the
performance hit is a combination of high resolution and GTK2 apps. I
posted an inquiry a while back on this list, never got a response.
I never seem to have any issues with QT apps like K3B or K9copy though.
