I just installed H12 Apprentice build 12.1.33 64-bit version on Windows7.
I have an Intel i5 3570K 3,4Ghz quad-core, 16Gb RAM and an AMD 7850.
If you need any other specs details, let me know.

I've searched the forum, but I didn't see anything that pointed me towards a solution to my problem.

The problem that I'm having is the following:
Once I place something in my scene, for example a simple box or grid, and I click on Geometry Select Mode (GSM), everything freezes for a couple of seconds, my screen goes black and when it comes back I get the message that my display driver crashed and has recovered.
Houdini itself then shows only black or white and I can do nothing about it except shut it down via Task Manager.
This happens only when I have something in the scene and then click on GSM.
As long as the scene is empty, I can click on GSM without any problems. Any other button works just fine, whether there's something in the scene or not.
I have upgraded my graphics card driver to the latest version I got from the website from AMD itself, rebooted, re-installed Houdini. Yet the problem stays.

Any help would be much appreciated!
Especially if this problem gets fixed within 2 weeks.
Because in 2 weeks I'm going to start a Houdini workshop in which case the program is pretty essential…
And just so you know; By reading the other threads, I realize it might have something to do with the fact I'm using an AMD card and/or it has something to do with OpenGL or OpenCL. If so, I have no experience in those matters.

Many thanks in advance!

We implemented a driver workaround for this issue in 12.1.37. Attempting to use OpenCL in Houdini still exhibits this problem however, and we've passed the issue onto the AMD driver team. You can still use OpenCL in non-graphical apps like hython and hbatch.

Little update.

I've been trying to see what works and what not and I noticed that it has something to do with how geometry is displayed.
If I display geometry in wireframe, the problem doesn't occur.
Having a grid in the scene and switching the display geometry to “smooth wire shaded”, the problem shows itself.
So I'm guessing it has something to do with the OpenGL stuff after all?

Thanks for the fast reply twod!
Viewing in wireframe will have to for now I suppose ^^

I'll try the 12.1.37 build once it's out and will post if I still have the issue or not.
And I'll do some research on OpenCL, because I have no idea what that is…

If you scroll down to the Daily Builds section of this page [sidefx.com], then you can get 12.1.75.

If you don't know what OpenCL is, you don't need to worry around running into bugs associated with it (it is a library which allows Houdini to do some computation the GPU, similar to CUDA, such as fluid sims).

Ooohhh, missed that one (d'oh). Thanks for pointing that out!
And sorry for me not noticing that myself…

Tested it and it works like a charm!
