Description of problem: Version-Release number of selected component (if applicable): libXcomposite-0.4.0-4.fc9.i386 xorg-x11-drv-ati-6.8.0-3.fc9.i386 xorg-x11-server-Xorg-1.4.99.901-8.20080310.fc9.i386 How reproducible: Use the default composite extension, try to load X, it will crash with a stack dump (will provide in a bit) Steps to Reproduce: 1. Launch X as a normal user (startx) or use KDM (KDE 4.x) 2. X server will crash with segfault and produce a dump 3. Actual results: Crashes when composite is attempted to be used Expected results: Application requesting composite launches normally. Additional info: Rawhide snapshot. I'll provide stackdump later today.
Note: I am use XAA no EXA for software acceleration kdeinit4: Got EXEC_NEW '/usr/local/kde4/bin/kgpg' from launcher. kdeinit4: preparing to launch /usr/local/kde4/bin/kgpg 0: X(xf86SigHandler+0x79) [0x80bc2d9] 1: [0x131400] 2: X(miHandleValidateExposures+0x37) [0x8127827] 3: X(UnmapWindow+0x1f8) [0x80702c8] 4: X(compFreeClientWindow+0x2d3) [0x8143b43] 5: X [0x813f604] 6: X(FreeResource+0x10c) [0x806dacc] 7: X(compUnredirectWindow+0x8b) [0x8142f0b] 8: X [0x813fe5c] 9: X [0x8127e45] 10: X [0x8127e57] 11: X(miChangeSaveUnder+0x6b) [0x8127efb] 12: X(MapWindow+0x37b) [0x8070a2b] 13: X(ProcMapWindow+0x69) [0x8085119] 14: X(Dispatch+0x34f) [0x808599f] 15: X(main+0x47d) [0x806b31d] 16: /lib/libc.so.6(__libc_start_main+0xe6) [0x418606] 17: X(FontFileCompleteXLFD+0x22d) [0x806a701]
I should also note I am building KDE '4.1' from their svn trunk so I don't know if this is triggering some new bug in Xcomposite.

This is quite certainly not stacktrace from Xorg. Trying compiz, but not sure.
This comes from KDE 4.x (in this case KDE 4.1) not compiz, Kwin also supports composite effects like compiz does. This bug is also logged in https://bugs.freedesktop.org/show_bug.cgi?id=15100
The stacktrace is from Xorg (libXcomposite and core X server)
Note, disabling backing store in xorg.conf gets me no crashing. Option "BackingStore" "false"
Lower priority, still a bug, but this is totally workaroundable.
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
Oh close this, we're in KMS now, and this bug is totally moot.
