Strange rendering artefacts visible in terminal

Created attachment 188350 [details] Screenshot illustrating the problem Since some time, I'm seeing strange rendering artefacts in gnome-terminal. See the attached screenshot to see how it looks like. Sometimes scrolling the widget up and down "fixes" the problem, but after a while the issue starts to show up again. I'm not sure this is specific to gnome-terminal, so feel free to reassign to another product if this is a known issue. Please let me know if you have any pointers, since I couldn't find anything!
Maybe a graphics driver bug?
The screenshot in bug 650863 looks a bit similar... Do you run metacity, or gnome-shell? If metacity, is compositing enabled or disabled?
I'm using metacity with the compositor enabled on a Intel graphics card in a desktop computer: 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02)
Can you check if the same happens with compositor disabled? If not, then -> metacity and you're out of luck since the compositor isn't maintained, afaik.
Created attachment 188523 [details] Another screenshot Another screenshot with metacity with compositor disabled. These are a few lines from a gnome-terminal window with top(1) running after disabling the compositor and restarting metacity completely.
<chpe> Company: any idea what could cause a rendering problem like in #650819 ? <Company> chpe: graphics driver, 1 pixel off in gdk_window_move_region() region, similar problem in X, (RGBA visual in use and) forgetting to clear something chpe: i can find lots of reasons that might result in output like that :/ <Company> could also be someone getting the rowstride wrong somewhere <chpe> hmm. I guess transparency / rgba visual does come into it, since I've never seen that problem
<Company> chpe: <ickle> it's a driver bug of some sort, tiling/fencing likely. So I'm afraid this is NOTGNOME. Sorry! If the driver version is recent-ish an upstream bug report might make sense, but the original version says you're running GNOME 2.30 and I guess the driver is similaryly old too?
While I'm using Gnome 2.30.x (actually, a 2.30 and 2.32 mix), the XOrg intel graphics driver I'm using isxserver-xorg-video-intel 2.15.0. According to http://intellinuxgraphics.org/2011Q1.html this is a fairly recent stable release, which is recommended for ordinary users according to the instructions on http://intellinuxgraphics.org/download.html. Any clue where my report is most appropriate? Xorg? Intel driver? GTK+?
To the intel driver delevolpers, I think.
