Thanks for your report. Unfortunatelly your backtrace this of little use, as there are debugging symbols missing. Please see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports for details. Also you should provide details on your hardware. Do you have an NVidia card using the binary nvidia driver? Also make sure you have the blur effect disabled: Open .kde/share/config/kwinrc in a text editor and check if kwin4_effect_blurEnabled in the plugins section is set to false.
No response.
Hi Dominik, Sorry for the late response. I had indeed the blur effect enabled... I disabled it and since one week didn't get the error at boot time. I change the resolution to fixed. Thank you for your help, Gianni
