[vtkusers] Rendering in a thread causes "Xlib: unexpected async reply"

[Stefan Bruckner]

In MY code I don't make X calls at all, this is done in Qt and VTK. I
suppose hat the QThread class does all the plattform-specific stuff,
such as this call (at least the Qt documentation suggests that) ...

Hi,
you could try calling XInitThreads() before making any X calls in your
code. -Jeff
