[vtkusers] X Error: BadWindow, vtk5.8.0, Qt4.6.2

[Clinton Stimpson]

You can mix debug and release of Qt or VTK on Linux and be just fine.
To debug this, I would suggest you set a breakpoint in _XError() and run your 
app with the -sync option.  QApplication will see the -sync, and set it up so 
that every X call will be synchronized with the X server and errors reported 
immediately.  It'll stop at the code that causes the error, instead of some 
time later in some irrelevant code.
