This is a RFC because I don't really know what I'm doing here. But we have this problem with AMD and KWin already for quite a long time and I hope it can be fixed now.
I followed the debug output and tried this guard. On my system this fixed the issue with Alt+Tab crashing KWin. Still this might be not the right solution to the problem. According to git-blame 330d0607 was the last time this condition was touched.
