Comment 1 Nate Graham 2023-05-15 18:25:17 UTC

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #4  0x00007f8f23f31d60 in KDecoration2::Decoration::shadow() const () from /lib64/libkdecorations2.so.5
> #5  0x00007f8f23ac3ef1 in ?? () from /usr/lib64/qt5/qml/org/kde/kwin/private/kdecoration/libkdecorationprivatedeclarative.so

Could you please install debug symbols for kdecoration and 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 for details about how to do this.
Thanks again!
