How reproducible:
Use the default composite extension, try to load X, it will crash with a stack

Comment 2 Shawn Starr 2008-03-17 20:23:24 EDT
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.

Xorg crash with full debug
Comment 5 Matěj Cepl 2008-03-18 07:23:20 EDT
This is quite certainly not stacktrace from Xorg. Trying compiz, but not sure.
Comment 6 Shawn Starr 2008-03-18 10:42:57 EDT
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
Comment 7 Shawn Starr 2008-03-18 10:43:57 EDT
The stacktrace is from Xorg (libXcomposite and core X server)
Comment 8 Shawn Starr 2008-03-19 00:07:40 EDT
Note, disabling backing store in xorg.conf gets me no crashing.

Option      "BackingStore" "false"
Comment 9 Shawn Starr 2008-05-09 11:56:53 EDT
Lower priority, still a bug, but this is totally workaroundable.
Comment 10 Bug Zapper 2008-05-14 02:40:21 EDT
Changing version to '9' as part of upcoming Fedora 9 GA.

Oh close this, we're in KMS now, and this bug is totally moot.
