Unfortunately the backtrace is incomplete and missing debug symbols that we need to figure out exactly what's going wrong: #6 0x00007f1c99095f51 in () at /lib64/libkwin4_effect_builtins.so.1 #7 0x00007f1c99096ccb in () at /lib64/libkwin4_effect_builtins.so.1 Could you please install debug symbols for kwin, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Thanks! Apparently the reason installing the debuginfo didn't work earlier was because of a version mismatch as I hadn't updated in a while. After updating and doing it again I got this: Application: Kwin (kwin_x11), signal: Segmentation fault Content of s_kcrashErrorMessage: [Current thread is 1 (Thread 0x7f5da15d0980 (LWP 6623))] [KCrash

Now we can tell that the problem is caused by the Dim Inactive effect. As a workaround, are you able to stop the crash by disabling that effect? Yes, the crash does not happen if dim inactive is disabled.
