[Xquartz-dev] failed to bind to surface errors

Hi, We have an X11 application that is generating "failed to bind to surface" errors on some OpenGL windows. We are running locally on the console (not remote GLX), and the error occurs in transient dialogs that pop up. The first time a window comes up things are fine. The error occurs after the containing window is dismissed (XtPopdown) and then popped back up (XtPopup). The error seems to occur when we call glXMakeCurrent() on the OpenGL window in this dialog. All other widgets in the dialog are fine - only the OpenGL widget appears to be affected. The OpenGL window does continue to receive mouse input - we just can't draw to it. Any suggestions would be much appreciated! -Mike
