Description Shawn Starr 2008-03-17 23:56:57 UTC
Description of problem:

Version-Release number of selected component (if applicable):


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
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.

Comment 2 Shawn Starr 2008-03-18 00:23:24 UTC
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 11:23:20 UTC
This is quite certainly not stacktrace from Xorg. Trying compiz, but not sure.

Comment 6 Shawn Starr 2008-03-18 14:42:57 UTC
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 14:43:57 UTC
The stacktrace is from Xorg (libXcomposite and core X server)

Comment 8 Shawn Starr 2008-03-19 04:07:40 UTC
Note, disabling backing store in xorg.conf gets me no crashing.

Option      "BackingStore" "false"

Comment 9 Shawn Starr 2008-05-09 15:56:53 UTC
Lower priority, still a bug, but this is totally workaroundable.

Comment 10 Bug Zapper 2008-05-14 06:40:21 UTC
Changing version to '9' as part of upcoming Fedora 9 GA.

Comment 11 Shawn Starr 2009-03-19 06:00:03 UTC
Oh close this, we're in KMS now, and this bug is totally moot.
