We have not seen this on our dashboards, where we test on quite a few
Windows variants, with different cards/drivers. Could you be more
specific, i.e. what version of VTK, what graphics card/Windows version
are you using and do you get any kind of backtrace?

VTK can build against Mesa to use software rendering, Windows has not
had any issues I have been aware of. Can you download a ParaView 3.10
rc (they use the same charts, and try charts in there to rule out any
kind of build issue.

Do you mean the 3D widgets? They are OpenGL, and it is possible the
charts are using something in OpenGL that the widgets are not.
