It is REALLY annoying.  AFAICR, I've seen this behaviour since about
driver version 6111.  I've tried to make a test case that reproduces
this bug, but it's unfortunately still quite complex.  It makes use of
a deliberately broken version of my vtkFlRenderWindowInteractor.  In
the non-broken version, the code passes an X11 DisplayId and a
WindowId (coming from the FLTK library) for VTK to render to.  The
broken version only passes a WindowId, so VTK has to create its own
DisplayId to render to the passed WindowId.

This used to work fine in previous releases of the NV driver, but now
it causes these REALLY annoying temporary system freezes.  AFAIK,
NVidia has not made ANY kind of statement in this regard.

See here for my test setup and some ancillary information:

Good luck,
