Dear all, I find that the error message is: (moblin-panel-applications:1845): ClutterGLX-CRITICAL **: Unable to make the stage window 0xc00006 the current GLX drawable
And I also find a bug report looks like that. https://bugs.launchpad.net/ubuntu/+source/gnome-games/+bug/428396 In the mutter-moblin source I find that error ocurred while calling [panel = mpl_panel_clutter_new (MPL_PANEL_APPLICATIONS, _("applications"), NULL,"applications-button", TRUE);]. And perhaps finally it calls [clutter_x11_set_stage_foreign].
