[vtk-developers] Rendering hangs in viewport

[Berk Geveci]

We use 64 bit atomic integer for timestamp on 64 bit Windows builds. We
can't use 64 bit on 32 bit builds because not all versions of Windows
support 64 bit atomic ints on 32 bit systems. It is also not possible to
check this at compile time as it is a runtime issue. The simplest fix is to
just compile a 64 bit binary.

Best,
