Red Hat Bugzilla – Bug 667124
artifacts visible on scroll
Last modified: 2011-01-10 03:51:36 EST
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
Created attachment 471679 [details]
See the area enclosed in red
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.
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.
