Version: (using KDE 4.4.0) Compiler: as per 4.4.0-8.fc12 x86_64 OS: Linux Installed from: Fedora RPMs kwin frequently freezes for ~10 secs and occasionally crashes while I drag a window across monitors. Mouse cursor still active but all other GUI elements freeze. ssh sessions, services, etc connected to workstation unaffected. Compiz enabled. backtrace: Application: KWin (kwin), signal: Segmentation fault 82 T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS) [KCrash Handler] #5 memcpy () at ../sysdeps/x86_64/memcpy.S:267 #6 0x00007f1eab7a999f in ??
