I don't know if this can be related, but I've also monitored the kwinrc content and it seems that upon any setting changes, the files goes from 25 to ~250 lines (somehow understandable, but... hard to debug). Initially, the line setting the OpenGL backend ("Backend=OpenGL") is not present, but after the setting change described above, it shows up.
