See the attached screenshot taken with: import -display :0.0 -window root ff-artifacts.png The area circled in red has artifacts due to the overlying terminal window. They appear after scrolling the firefox content. This happens with general.smoothScroll on or off. $ rpm -q xorg-x11-drv-intel xorg-x11-server-Xorg kernel firefox xorg-x11-drv-intel-2.12.0-6.fc14.1.i686 xorg-x11-server-Xorg-1.9.3-3.fc14.i686 kernel-2.6.35.10-72.fc14.i686 firefox-3.6.13-1.fc14.i686

I should also add: $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) Also I don't see the issue in other apps, but I do see flickering in the problematic area in other apps, but they do always draw in a consistent state, when you stop scrolling. Also it doesn't happen immediately, but may take 10-20s of scrolling in firefox to show the issue
This one is a firefox bug fixed in rawhide.
Cool thanks. Will it be backported. It's a minor issue so I guess not. Do you have a pointer to the bug or patch for the issue?
It's fixed by new layer engine in ff4 and it's not going to be backported to 3.6 line.
