Not really random actually, happens only with some invalid(?) themes. Using Ubuntu Ambience by half-left (http://gnome-shell.deviantart.com/gallery/28081982) for few days now and 'bug' is gone.
@Rene: I'm using the GNOME Shell default theme. On my side the artefacts come and go during the same session. It is not systematic. I even think it sometimes doesn't even happen. I haven't tried changing theme though.
Can it confirm exactly for Thinkpad T60 RV515 (Radeon X1300) Gnome-Sehll default theme Bug #707696 seems to be a duplicate.

Artefacts are gone really! This is the first time that I can use gnome-shell for serious work... May be this is some side effect. Contains the default theme really the 'bug'? Anyway, all these random black pixels on the close button are gone. The black background someone is gone too... Now we to found out what's really is going on.
Possibly related to bug # 679414

Also seen on Thinkpad T60p with ATI Technologies Inc M56GL [Mobility FireGL V5200] xorg-x11-drv-ati-6.14.1-2.20110525gitfe5c42f51.fc15.i686 Happens sporadically but usually seen within a few hours.
Still present in F16
Still present in F17. For me it's also on RV515 and it has all the same symptoms. * Missing characters * Characters rendered twice with offset as in attachment 1 [details] * Text backgrounds black * Window corners missing or black And it is not a problem all the time. I can run the computer for weeks without artifacts and then suddenly they start to show up. I have the computer turned on 24/7 with 30-50 windows open most of the time.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This bug is still present in Fedora 17 as of January 2013.
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
