I have suffered from this bug for quite a long time from KDE 4.9 to KDE 4.10.4 and from Ubuntu 12.10 to 13.04. There is a post about some details on this bug in AMD Linux bug report:
Bug 657 - X server crashes when resizing or mapping RGBA window (fbCopyNtoN) http://ati.cchtml.com/show_bug.cgi?id=657
It seems that this problem has been existed for quite a long time.
