Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), * X server log file (/var/log/Xorg.*.log) * 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. Created attachment 482734 [details] /etc/X11/xorg.conf.d/10-radeon.conf No xorg.conf, but I do have the attached file to turn color tiling off.

Requested log and configuration files attached. All of these were
gathered after a KWin crash which was caused by the NULL pointer
dereference.
(I can reliably reproduce this when unlocking an OpenGL screensaver,
such as GLMatrix, when running KDE. It doesn't happen every time. If
the unlock dialog is rendered correctly, then the crash will *not*
occur; if the unlock dialog is mostly invisible then I know that the
crash will occur after I unlock the screen saver.)
> Option "ColorTiling" "off"
Actually, Xserver 1.10 has landed in F15/updates-testing so you may be able to get rid off this configuration file as well.
However, we shouldn't crash anyway. Passing the bug to developers.
I suspect that the root cause will be addressed by the patch in https://bugs.freedesktop.org/show_bug.cgi?id=35452. I don't have Fedora on this system anymore, but this should be fixed in 1.10.1-14: * Thu Apr 28 2011 Dave Airlie <airlied> 1.10.1-14 - backport upstream DRI2 fixes that are being screwed around with upstream |
