But it sounds entirely plausible. The X server's GLX code has a bug where it may randomly return a bogus visual/fbconfig; perhaps it ended up not having stencil, and we crashed? That bug is fixed in X server git, and the upcoming 1.15.1 and 1.14.6 releases (due any day now). Alternatively, you could try asking KWin to use EGL: KWIN_OPENGL_INTERFACE=egl kwin --replace & Does either of those fix this issue for you?
