R2008 - Fully Direct3D certified driver shows yellow dot problem.

[RGvanEijk]

It's the same problem as in R11: Yellow dots appear in the sketch when you activate a sketch command. See the attachment.

I have an nVidia Quadro FX330 with driver .9136 running on Direct3D. It seems that I have to switch to OpenGL

I will attach information in my next post.

Have you rebooted the computer? I've had that show up when my video memory
needed to be cleared.

I get this at work on a regular basis with IV11. I'm at home now and I
don't remember the computer specs. Restarting Inventor solves the problem.

We are looking at this. Please send me any information that you think is important.

Please be sure that:
1) all traces of ATI drivers have been removed using Add Remove Programs.
2) Inventor is excluded from Nview.

If I reboot the computer the problem is gone, I know.
But they need to know that this problem still exists.

Initial investigation indicates that this is related to the amount of memory (or address space) in use. Testing on a system with GB of physical memory, We couldn't see yellow dots until we loaded a very large assembly. Then they showed up.

Does this match the observations of this thread?

We have found the problem and have a fix. It is _not_ a graphics driver problem, it is in our graphics layer code.

The problem is caused by the graphics HW using all its available video memory for graphics windows. The Quadro FX 330 has 64 MB of video memory so if you create several large graphics windows, even at 1280x1024, you will consume all the video memory available.

When this happens, Direct3D will correctly report a failure to optain more video memory for the next graphics window. We were neglecting to propagate this error condition up through our code so our graphics window code would respond accordingly.

With the fix we have just implemented in our Development code, we have verified that we now handle this error condition properly and the Inventor graphics windows work correctly.

The work-around in the meantime is to avoid having several graphics windows open at the same time. In our testing, without the fix, we could open 7 graphics windows before the problem occurred. With the fix we see no limit; for example, we have tried having 60 graphics windows open at the same time without seeing any problem.

Thanks to all who reported this problem and helped us track down the source of the problem in our graphics layer code.

Awesome! I usually kept a few graphic windows opened all because of the yellow dots. Looking forward to open a million. 😉

Great Norbert! Thanks for the information.

What you describe is exactly what happens. I had quite a bit of windows open at the time.

Do you know if SP1 will contain this fix?
