[vtkusers] Remote Desktop and the VTK window

[Shawn Waldon]

Hi Doug,

Windows 10 supports OpenGL 3.2 (which VTK's OpenGL2 backend uses) over
remote desktop... but it depends how the user initially logs into the
machine.  If the initial login is over remote desktop, Windows decides "you
don't need any graphics resources" and doesn't initialize the graphics
card.  In this case, you get the behavior you describe where VTK crashes
upon initialization.  However, if you initially log in locally and leave
the session up, logging in over remote desktop gets the initialized
graphics resources and VTK applications work fine.

Unfortunately I don't have a good solution for you if the developers who
work from home are always working remotely.  Hopefully this helps though,

Shawn
