Description of problem: After I started firefox, I see garbled fonts (see screenshots) after some little amount of time. This issue is also observed by me in other GTK2 application I'm using - GQview. Looks like Qt application I'm using (Psi) doesn't produces this issue by itself but when Firefox corrupts fonts, Psi is also shows us damaged ones. I can suppose that it's due to some GTK2-X11 font relations but I'm not sure. Version-Release number of selected component (if applicable): Fedora 9-Preview xorg-x11-server-Xorg-1.4.99.901-26.20080415.fc9.ppc gtk2-2.12.9-5.fc9.ppc firefox-3.0-0.59.beta5.fc9.ppc How reproducible: Always Steps to Reproduce: 1. Start Firefox 2. Wait until it stops consuming 90+ percents of CPU and will be at least responsible 3. Surf the web a little 4. See corrupted fonts Actual results: http://peter.fedorapeople.org/bad_fonts.png http://peter.fedorapeople.org/bad_fonts2.png http://peter.fedorapeople.org/bad_fonts3.png Also there is a screenshot with Psi: http://peter.fedorapeople.org/bad_fonts_psi.png

Commenting out Option "AccelMethod" "exa" solved the issue. Since EXA is obsolete, it's not a solution but rather a workaround. See also http://bugs.freedesktop.org/show_bug.cgi?id=15611

Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This issue was gone, then I switched to 16-bit mode. See also BZ #473440 https://bugzilla.redhat.com/show_bug.cgi?id=473440 Probably these two tickets are symptoms of one common issue?
I'm also seeing garbled fonts on up-to-date F10 on a ThinkPad R50 with RV250 [Mobility FireGL 9000] (rev 02). All fonts of all X applications/toolkits are garbled, including gdm. I.e. the fonts are garbled before I even log in, so this seems unrelated to the length of the session or load. Fonts are ok when I use the F10 preview live cd, so the problem seems to have appeared after an update. I installed today from preview live cd ('install to hard drive'), then updated to current F10 (release, no rawhide) with yum. I now have xorg-x11-server-Xorg-1.5.3-6.fc10.i386 xorg-x11-drv-ati-6.9.0-62.fc10.i386 kernel-2.6.27.7-134.fc10.i686 Will attach Xorg.0.log.

Tested with the ATI driver version from F10 release day, xorg-x11-drv-ati-6.9.0-54, and it works. All other Xorg packages are the same. So, the font rendering apparently breaks between 54 and 62.
Are you working on x86 or powerpc platform? I still have no luck with latest xorg-x11-drv-ato for F10 (see attached file)
Created attachment 327881 [details] Text rendering with xorg-x11-drv-ati-6.9.0-63.fc10.ppc. Text rendering with xorg-x11-drv-ati-6.9.0-63.fc10.ppc. Note the yellow "echo" at the end of some words.
Good news is that I clearly see some progress - my only Qt application (Psi) seems no longer affected by this bug. Also, I can read (and write) texts nowadays - this yellow tail is the only issue remaining. It looks like something "eats" tails of some words and replaces eaten parts with their yellow shadows :). I'll try latest git version.
I've only seen this problem on a ThinkPad R50 (Pentium M) and an even older ThinkPad A30 (Pentium III Mobile, Radeon Mobility M6 LY), which are both x86. I don't have access to the machines right now (I'm away for Christmas), so I cannot test the git version or such.
Seeing some font corruption on my Compaq Presario X1000 system with Radeon Mobility 9000 graphics. Fonts have some "static" above or below lines of text in some cases. Will attach screenshot. This is with xorg-x11-drv-ati-6.9.0-63.fc10.i386

Problem mentioned in comments 16 and 17 and FreeDesktop.org bug 19363 can be worked around by Option "RenderAccel" "off" in xorg.conf. Also it does not appear to happen in the latest -git version (with RenderAccel enabled). Maybe something can be backported?
Today's git ( d5cb24075928690377fd2dfaa32abfebff9990df ) works for me! Still yellow echo at the end of the words, but I've got glxgears with 700+ fps and correctly drawтб even in 24-bit color!
