Version-Release number of selected component (if applicable): kernel-2.6.38.6-27.fc15.x86_64 xorg-x11-drv-ati-6.14.1-1.20110504gita6d2dba6.fc15.x86_64 mesa-dri-drivers-7.11-0.9.20110509.0.fc15.x86_64 How reproducible: Steps to Reproduce: 1. Use GNOME3 (do not know if this is realted or not) 2. Use the computer for a while. Surf the web, or anything. 3. Actual results: Sometime screen loses parts. Expected results: The text should always be fully visual. Additional info: I do not know if this is related, but from time to time I may lose the output in gnome-terminal. Sometimes it is just odd-colord outputs, sometimes it all the grey output.

Exactly same screen corruption as shown on the attached *.png for me. This is on a Thinkpad T60, Radeon X1300 / driver rv515, 32 bit Fedora 15 without xorg.conf Latest kernel / xorg-x11-drv-ati / mesa update from koji doesn't fix this very ugly problem. I think the chars-loses-parts-issue are for xft'ed chars only. For example if I enable xft for conky chars are partially lost. Chars without enabled xft are fine. As an addition the chars on title bar of gnome-shell are changes randomly. Sometimes they are bold without xft, sometimes they are o.k. If I restart gnome-shell with alt -> f2 -> restart all is o.k. for while... Some times later the damned "chars-looses-parts" issue is visible once again.
More detailed issues are found: Sometimes while loading a web page using epiphany the defined colors are ignored, for example red fonts are shown as black fonts, the defined color is lost. gnome-shell restart is the fixes that ;-)
Sorry for the typos at last posting... Anyway I can help debugging that. The Radeon rv5* mobility series are popular at present... Compiz works fast and without these ugly damned randomized font garbage...
Changing gnome shell theme from default to (for example) the Ubuntu Ambience by half-left at http://gnome-shell.deviantart.com/gallery/28081982 is the fix (or workaround). See https://bugzilla.redhat.com/show_bug.cgi?id=692191
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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" (top right of this page) 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
