Description Pete Zaitcev 2009-07-19 01:05:18 UTC 
Description of problem:

X crashes when moving a window, there's no kernel oops or a traceback in
Xorg.0.log.

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

xorg-x11-server-Xorg-1.6.99-9.20090706.fc12.x86_64
xorg-x11-drv-ati-6.12.2-19.fc12.x86_64

How reproducible:

100% on the given computer

Steps to Reproduce:
1. startx
2. Start gnome-terminal
3. Try to move it
  
Actual results:

"The 4 arrows" cursor moves about a pixel or two, then crash.

Expected results:

No crash, window is moved.

Additional info:

This is 100% crash on a common operation, right after start, so I was
shocked a bit. But I have a different system which runs VESA driver
and same Xorg, that one works. I'm attaching yum.log.

Xorg.0.log

No traceback, X server exits abrubtly.

yum.log

I think I caught this over the last update, July 17.

stderr of startx

Looks like it's the new pixman, the error log of startx contains:

X: pixman-region.c:457: pixman_region_copy: Assertion `pixman_region_selfcheck (src)' failed.

And then the server crashes. Can you guys at least restore the text
console when you crash?
Comment 4 Pete Zaitcev 2009-07-19 01:34:36 UTC 
Same story with pixman-0.5.16-1.fc12 -- crash on the first move.
Comment 5 Søren Sandmann Pedersen 2009-07-19 04:00:03 UTC 
Can you get a backtrace with gdb from another machine?

stack trace

The stack trace is incomplete, because I haven't all needed debuginfos installed. I'll post better one tomorrow.
Comment 7 Søren Sandmann Pedersen 2009-07-19 16:14:15 UTC 
David, is this with the latest rawhide X server?
Comment 8 Matěj Cepl 2009-07-20 08:07:51 UTC 
There is nothing to triage here.

Switching to ASSIGNED so that developers have responsibility to do whatever they want to do with it.
Comment 9 Pete Zaitcev 2009-07-20 16:43:36 UTC 
Updated to xorg-x11-server-Xorg-1.6.99-14.20090715.fc12.x86_64.
Problem is gone. Notice, pixman was not updated. It must have been
a flag day between X server and pixman.
Comment 10 Joachim Frieben 2009-07-22 08:59:08 UTC 
Same here: bug 513001. Issue can be worked around by adding '"AccelMethod" "xaa"' to xorg.conf.
