TOP freezing problem (2023.12230)

Bugs
1

Hello TD crew,

I don’t know if it’s an actual bug, but I don’t know what to do :frowning:

I’m using TD 2023.12230 in No-Commercial version on Windows 10

My PC is a MSI Laptop Vector GP66 with 3080 and I7 12th with 16GB RAM
Nvidia Driver version 572.70

Starting from the default patch I add a Window COMP and I set it to Noborders, Monitor 1 and FILL
I link the last TOP on the Windows component and open it a separate Window.
The monitor 1 is connected via HDMI to an Acer Projector that I usually use and never gave me such a problem.

All works fine, but if I put a LEVEL TOP just before the last TOP and I change the luma or the brightness level TD freezes.
I reinstalled the whole Widnows from scratch, same thing.
I don’t really understand what is the problem.

Thank you

PS: please see the video attached.

Hi @Simplo,

If TouchDesigner is hanging, you can create a .dmp file or Crash report. On Windows, this can be done using the Windows Task Manager and right clicking on the process and chooseing ‘Create Dump File’. It’s also possible using WinDbg, see Using_WinDbg_to_Debug_Crashes. On macOS, see macOS Crash logs.

(Troubleshooting in TouchDesigner - Derivative)

I think the video might be unrelated to this hang.

Sorry, I posted the wrong video, please take alook at this: https://1drv.ms/v/s!AvdznCySJn-O0KkfBStHxks6Z709Iw?e=xRER1v

As soon as possible I will try to get the dump file when I’ll be back in the theatre.

Thank you
Simone

Hi there, it freezed again even without the projector, just sliding a monochrome’s paameter.
Here is the dump form the windows Task Manager (above 3GB).
TouchDesigner.DMP

Thank you

Hi @Simplo,

Thanks, we will have a look.
in the meantime, have you tried going back a version (or to a version you remember working) to see if this behavior changes?

cheers

Hi @Simplo

This looks to be related to another bug (Touchdesigner stuck when customzing component - Bugs - TouchDesigner forum). Can you try downgrading your Nvidia drivers to the 555.xx series to see if that fixes your issue.

Thanks,

Huck

Hi Huck, thank you for your reply, I would like to try, but in the nVidia site the older downloadable driver is the 560.94, I’m trying to find a place to download a 555.xx

Before reinstalling it seems to me I had 2023.12120, same problem.

Hi @Simplo

Yep it might be a bit harder to find the older versions, you can try doing a Google search since Nvidia’s archives don’t go back that far, but the drivers are still on their site if you find them via Google.

So far we’ve had no luck reproduce this issue on any of the laptops we have in-house.

One thing you could try is downgrading your TD builds to see if anything earlier doesn’t have this issue. If you are able to find a build that works, then that may help us diagnose the issue.

I found it! Thank you! Just installed, next time in theatre I will try.

As soon as possible I’ll trym also trying with the nVidia drivers downgrade as suggested by Huck

It seems that downgrading the nVidia drivers fixed the problem.
3 hours of live coding in TD with the projector active and no crashes.
But now I’m working with a very old nVidia driver 555.x, as suggested by huck.
