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? Tested by applying eec04d76a39a7334de4e00ef9f0f6e44c92b3d91 on top of 1.15.0. Cannot reproduce the bug anymore. *** Bug 82793 has been marked as a duplicate of this bug. *** |
