I ssh with "-Y"  from my Mac desktop to a GPU computer and process my data there. Quite often I need to look at the 3D volumes with chimera. This had been working nicely for long time. But all suddenly it stopped working and game the error 3:

X Error of failed request:  GLXBadCurrentWindow

  Major opcode of failed request:  149 (GLX)

  Minor opcode of failed request:  5 (X_GLXMakeCurrent)

  Serial number of failed request:  1400

  Current serial number in output stream:  1400

Did anyone encounter the same error? Any suggestions or tips to overcome this problem would be appreciated. 

Thanks,

Zongli
