TouchDesigner freezes on startup with AMD RX 6600 on Windows 11

Bugs
1

Hi Touch Designer Team,

Since upgrading to Windows 11, TouchDesigner opens, works for a split second, then freezes. Sometimes I’m able to “End Task”, but other times I have to restart my computer.

I have an AMD RX 6600 and an 11th Gen Intel(R) Core™ i9-11900K CPU

I’ve tried Touch Designer versions 2025, 2023 and 2022. I think it’s a GPU driver issue, because I had a similar problem with OBS after upgrading to Windows 11. I’ve now downgraded my AMD Driver to 23.11.1, and that fixed the OBS issue. It didn’t fix Touch Designer though.

If I disable my AMD GPU, TouchDesigner doesn’t freeze, so I know it’s something to do with my graphics card and W11. It worked fine before I updated.

Any help appreciated!

Hello @bosterho

Are any dump files being generated when TouchDesigner crashes? If not, you can try to create them by following the instructions at the link below:

Once you have the dump files, please compress them and send them to support so we can take a closer look.

Hi Guillaume,

Dump files aren’t being generated.

Thanks for sharing WinDbg. Very cool!

I have a debug log and call stack now which document it.

AI is pointing out this part:

Thread 0: (Main thread - HUNG)
win32u!NtGdiDdDDIDestroyAllocation2
D3D12Core!CallAndLogImpl
D3D12Core!NDXGI::CDevice::DeallocateCB_0022
amdxc64!boost::serialization::singleton (AMD shader compiler)

Suggesting that TouchDesigner’s main thread is stuck destroying/deallocating an AMD GPU resource.

It appears to be an AMD driver bug.

I’ll get in touch with support

It appears with my non-commercial license I only get General Support, and I don’t see a way to reach out directly, other than posting on the forums.

I copy and pasted the text from the main window in WinDbg into a txt file.

Then I did ~*k to show all threads, and copied the result into another txt file.

If you’re able to take a look or pass this along, it’d be much appreciated!

Thanks again.

We need a .dmp file to be generated. Sorry if I haven’t thought about it sooner, but there is a easier way to generate such a file with the Task Manager. When TouchDesigner freezes, right click on the process and select Create Memory Dump File.

Oh wow! All these years with windows and I never notice these things.

The DMP is quite large, so here is a dropbox link: Dropbox

It seems the hang is occurring when TD attempts to create a window, which often points to a graphics‑driver or display‑related issue. Before downgrading, were you already running the latest GPU drivers? If possible, try connecting a different monitor to rule out display‑specific problems. You could also experiment with changing the current monitor’s resolution or refresh rate, as some driver configurations can fail during swapchain or window creation.

Yes, I’ve tried both TouchDesigner 2023 and 2025 with the latest GPU Drivers.

Ok, I’ve tried a different monitor. Then I tried 1920x1080 at 100% resolution, then set the refresh rate to 30fps instead of the usual 60. I got the same result for all of these.

I notice something funny with the window, where it kind of jogs up right when it freezes:

By the way, I get the same thing when I do fresh settings, which don’t use Function Store. I’m pretty sure that’s not the cause.
