Well, I um'd and ah'd thinking about a way to use houdini when away from home. I need a powerful light laptop so finally splashed out on a Del XPS 15z. However, I think I have an openGl problem. Can anyone help me?

Please see attached images. One before I change my view, one after I change my view….I get this grid like vertical plane pop up!!

I was told by support to put in a line “HOUDINI_OGL_SOFTWARE = 1” in the houdini.env file. This did not work for me but it may work for you.

OK. In case it helps others. I tried to solve this on my own (Thanks sidefx). I resolved my issue by going to “display options” , then to the optimisation tab and unchecking the limit resolution box. Not sure what the consequences are but it got rid of all my viewport “artefacts”. Cheers Eric
