Huh, I've never seen this failure mode. 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?
