sometimes i also see this

From my experience messing with Renderman XPU, when I first downloaded it and my Houdini and Renderman versions were exactly matched the interactive viewport render worked great. Then I needed to update Houdini, and Pixar only puts out new renderman versions every few months so I thought I'd leave it and see. I don't remember if I tried it again that version or a couple later but the viewport render was broken the next time I did, and I could only render out to a Renderman window. A few Houdini updates later and Houdini starting crashing with some seemingly unrelated error on startup... which turned out to be that now having the 2 month old renderman version installed at all would crash it on startup and I had to remove it.

I can't imagine Arnold or Redshift did much better with integration and the houdini minor version probably needs to be frozen at whatever they built for to make sure it actually works like it's supposed to.
