[vtkusers] OpenGL2 + Qt5, is it supposed to work?

[Shawn Waldon]

Hi Tilman,

As far as I know it is supposed to work.  One application I work on has
been using the OpenGL2 backend with Qt5 since last January, but we used the
VTK that was current on master at the time rather than 7.0 (for other
features not Qt5 support).  I don't know of any major Qt5-related fixes
between 7.0 and then though.  I know the currrent master/7.1RC works since
we are using that now.  Come to think of it, there have been several fixes
in the OpenGL2 backend for various Intel onboard graphics chips since 7.0
so that may be your problem.  You should try master or the release
candidate for 7.1 and see if the problem still happens.

HTH,
Shawn
