[HOU-1554] vfb crashes

[LeoYfver]

We get crashes and freezes when rendering with ipr and vfb on many occasions. Its hard to track exactly when or why so I was thinking of putting up one example here for now.

Because these crashes and freezes are a bit random we only sometimes have a crashlog. What informationen do you usually want for these kind of errors. Maybe a debugging tool tracking memory or something?

this one crashed when selected framebuffer window and dragged it

I reported this a while back, Gosho found out that it is related to running low on system memory
This is how I got it to crash on my laptop..

Hello LeoYfver , I couldn't reproduce the crash on my side with your or newer nightly build, but I've got the same error "* Geometry node not found!". Issue is reported as HOU-1554 and will inform you when we know something more.
