I have Alienware R5 with GTX 1080 too. =T I'll keep searching for a solution. Have you tried reaching out to Sidefx.com? In the meanwhile, you can contact them about the issue. What they will ask you is to save out a file generated from Houdini and send it to them. (Help -> About Houdini -> click on “Show Details”. Click the "save” button at the bottom)

Did you try installing the latest driver of your gpu?

I actually reported this problem to Sidefx and they gave me a solution. Just wanted to update so people who stumblr upon this thread can have some hope. I updated all my drivers to the latest and it didn't really help but I uninstalled and re-installed to QT4 version instead of the latest. It started working smoothly. So there you go. Try QT4 if it doesn't work for you on production build.
