hi!
got problems with build 9.5.186, i was doodling with 9.1 apprentice until now.

it is some driver issue for sure ( i think)

sympthoms:

- i use dual monitor setup, on secondary whenever i scope channels, opens up channel editor, it crashes the app
- opening expression editor, and then selecting a node -> crash

it happens only when doing something on the secondary monitor.
downloaded the latest nvidia drivers

from crash log:
Caught signal 11
+0x69851623


system: xp sp3, quad core intel, nvidia quadro fx 1500

any ideas please?

Which video driver version are you running on? You can try updating to a 1XX.XX series driver or later.

runnig with 169.96, the latest for quadro fx 1500

Does it work if you first set the environment variable HOUDINI_OGL_DISABLE_FBO to 1?

To be clear, which exact build of Houdini are you running? 32-bit or 64-bit? The VC7 or VC8 version?

32bit vc8

i have set that env var, but still getting crashes.

I will remake some desktops, maybe something is changed there.
I'm saying this because i have a desktop where on the second monitor is a floating network editor, and when i try to put down a grid there, it behaves like it is a scene view. Instead of droppong down a node, i got message to put down thegrid like in scene view.

Or maybe you can see if it reproduces for you in a single monitor setup?

if i'm using only the primary display the everything is working fine.

just it is a bit annoying that can't use the extra space

What resolution are you running your dual setup at? The QuadroFX 1500 has 256MB of framebuffer space, I'm just wondering if perhaps it's running out of memory on the video card (while textures can be swapped out, not all the framebuffers can).

running on 1600*1200 on both, the strange thing that it worked with 9.1 flawlessly

You introduced that checkbox in the prefs -> Keep floating windows on top

When this is on, i even can't drag windows to the second monitor.

You introduced that checkbox in the prefs -> Keep floating windows on top

This preference and the “new feature” it introduced is now gone as of 9.5.189 on Windows. It wasn't needed on Windows anyways (floaters were on top by OS default, and it was almost impossible to work with Houdini with it off). So that should likely solve that issue.

hi!

back again, sorry

Now using only the primary display.
still getting crashes, and this time with editing expressions, hitting enter crashes the app, not all the time, but every five minutes.

Also another question:
having only an ambient and a point light in the scene, i want to change the ambient but nothing happens in the viewport, the point light reacts.

Is there any openGL issue or my card (quadroFX1500) is too old for this, 2 lights.
