[arch-general] Intel SNA artifacts in Firefox
Since the xf86-video-intel update that enabled SNA by default, I've noticed that some areas of some web pages (mostly flat backgrounds) in Firefox suffer from heavy graphical corruption, as if those areas are being used as rendering buffers elsewhere: bits of web pages from other tabs, etc... It goes away when I scroll the page. It happens regularly, every couple of minutes or more. This is on a Dell Latitude E5520 (Sandybridge i5) with KDE. I'm wondering if anyone else is seeing this?

Hello, chromium (v28) on Awesome seems to have the same problem. It isn't really bad so I just ignore it. --Chris Sakalis

Paul Similar thing happens to me with chrome and awesome. I think it happens since last two version of intel driver updates.
Chromium leaves strange artefacts after switching from the first (and only) search result on intel here...

so did you follow the instruction given during the intel upgrade by pacman: ------------ This driver now uses SNA as the default acceleration method. You can still fall back to UXA if you run into trouble. To do so, save a file with the following content as /etc/X11/xorg.conf.d/20-intel.conf : Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection ------------ i did that, and the artefacts are gone. -- phani.
