Interesting. Please add drm.debug=0x04 to the kernel command line, restart computer, and after reproducing the issue, attach
* your X server config file (/etc/X11/xorg.conf, if available),
* output of the dmesg command, and
* system log (/var/log/messages)
to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

dmesg command output
The problem reproduced with the drm.debug=0x04 kernel argument. I had to restart again due to X taking 100% of CPU issue and in that case the bug cannot be reproduced. When X is not consuming all my CPU power the problem appears.
No extra configuration file exists:
$ ls -al /etc/X11/xorg.conf
ls: cannot access /etc/X11/xorg.conf: No such file or directory
And my /var/log/messages log is empty:
$ ls -al /var/log/messages
-rw------- 1 root root 0 Σεπ 1 03:06 /var/log/messages
(In reply to comment #5) > And my /var/log/messages log is empty: > > $ ls -al /var/log/messages > -rw------- 1 root root 0 Σεπ 1 03:06 /var/log/messages Then you have some much bigger problems than just intel driver broken. This file should never be zero-length. Do you have any idea, what's going on? In the beginning, I was thought that /var/log/messages was deprecated in Fedora 15. However, it turned out to be an upgrade issue, when upgraded from F14 to F15. I was hit by bug 699198. I've resurrected my rsyslogd with a simple "systemctl enable rsyslog.service". I've reproduce again the issue and I am uploading the requested files. Thank you very much in advance. Created attachment 521187 [details]

Var log messages
Fixed on Fedora 16 for the background. The issue only remains for the foreground applications. If the same rendering solution can be applied for the windows, it would be great. Totally fixed on Fedora 17. Both background and foreground is rendered perfect on heavy CPU load and pager desktop switches. The ticket can be closed. Closing per comment #12, thanks! |
