TouchDesigner crashes when "Open as Seperate Window" to a second monitor


For some unknown reason, TD started to crash when I press “Open as Seperate Window” into a Window COMP and I choose my 2nd monitor as the target to create the window. If I select the primary monitor, it does not crash. Any help?

Thank you!


Could you send over the dmp file and CrashAutoSave toe file, if it created them?

@vassmal Do you have a MSI, ASUS, or Acer laptop? This is a known issue with the bloatware that comes installed on them, if you remove it the problem should go away. If you have one of these laptops search the forum for ‘bloatware’ and you’ll find tips of what to uninstall.

Second thing to do is make sure your graphic drivers are up to date.

I finally did a format to my PC (it was time) and the issue is fixed now. The big question-mark is that the problem started appearing suddenly, I did not change anything in the settings of my GPU or PC. I always use “Open as Separate Window” when I build a project, so I was using this all day and suddenly this crash started to happen. If this happens again I will send in this post. How can I get the dmp file and the CrashAutoSave toe file if this happens again, so I can send you?

Also, I have an Alienware (Dell) laptop with a RTX2070i Q-design GPU.

Same problem here. Started suddenly this morning without any changes on the settings. I am also on an alienware area 51m. Additionally, TD also freezes when I am double clicking and trying to open the ‘‘op create dialog’’, making td unsuable. Unfortunatly it doesn’t produce a CrashAutoSave toe file.
build 2020.23680

Update: I did a fresh install of windows and immidiatly installed TD. It was working fine, up until the point I started installing drivers. I am suspecting that alienware command center might be causing this . I just did a sencond windows install and Td is working again(fingers crossed) .

In this working case you ‘did not install alienware command center’ yet?

No I did not and everything seems to work fine until now

Hi, I confirm it’s the alienware command center. I installed it, the crash appeared, I uninstalled, the crash disappeared.

I am having the same issue. I uninstalled Alienware Command Center and will try again, but my preference would be to have both installed in the future. Let us know when this is resolved! Thanks for the help.

I am having the same issue. I tried uninstall alienware command center but still have the issue.

It also freeze if I try to open a pop up menu on a secondary monitor.
It seems to be a problem to create a window COMP on a secondary monitor added to another instance of TD.

If I try to create the window on monitor 0 and move to it to monitor 1, it works.
If I try to create the window on perform mode on monitor 1, it works.
If I try to create the windows on “separate window” on monitor 1, it freeze.

I tried disabling completely internal chipset and force to NVIDIA card but didn’t fix it. I try the contrary to force everything on the chipset but didn’t fix it either.

Sorry, no dmp file to share

Curious, usually Command Center has been the issue.

This might not be possible for you to test for us, but if you can… what happens if you use 2 external monitors and close your laptop monitor (ie run in clamshell mode). Any way you can connect 2 external outputs (monitors or projectors, whatever). I am wondering if the problem goes away and it works with 2 monitors when the internal GPU is out of the mix, this does point to the issue still being going from internal GPU to external. Although its not a solution, it would help us understand the situation.

For now I can’t do that test. As soon as I get the necessary monitors, I’ll tell you !

Thanks !

Have a nice day, everyone.
I have the same problem, any project immediately crashes when opened on a second monitor.
I am using build 2020.44350 (but this problem was with all versions of this year)
My DELL G7 17 7790 laptop:
processor: Intel Core i7 9750H (2600 MHz)
video card: NVIDIA GeForce RTX 2070 Max-Q (8 GB)
Windows 10 Home
I am using the latest drivers for DeLL and Nvidia
I read above that it is possible to uninstall Alienware, but it didn’t help me.
If someone solved this problem differently, I will be glad to any feedback.
Thank you!

I had a similar symptom and it stopped happening after uninstalling the alienware command center.

Hi Ben,

I have been experiencing a similar issue of TouchDesigner crashing when right-click opening on operator any floating window (like Parameters, or View, etc) if the Network is on the extended monitor.

I did several tests:

  1. running Network on a laptop screen, opening floating parameter window on a laptop screen, then moving that floating window to extended monitor, things working fine, no crashes.
  2. opening file and moving Network window to extended monitor, then trying to open a floating parameter window of operator, TD freezes and shows white screen. It does not create a crash file.
  3. I followed your suggestion to run TD in clamshell mode with two extended monitors attached: TD moved my Network to one of my monitors, opening floating windows on that same extended monitor doesn’t freeze TD and it works fine.
    I tried to leave the Network on the initial extended monitor and move the floating parameter window to the other monitor, still works. But when I tried to move the actual network to another external monitor and try to right-click and open the floating parameter window, it goes white and is showing (Not Responding) and freezes.

My observation: TD freezes and doesn’t respond when after opening a file you try to migrate the Network window to another monitor, it doesn’t allow to open any extra windows. I had other application windows running simultaneously and it didn’t cause the issue. Only when I moved the main TD network window to another monitor, this issue started to appear.

I am using an ASUS ROG G703 PC laptop. (Intel Core i7-8750H CPU 2.20 GHz, NVIDIA GeForce RTX 2080) I followed the steps to remove any visible bloatware and disable apps on a start. I do see that there are a bunch of apps running in the background, including Armory Crate that I did not dare to remove, but no other apps besides TouchDesigner are running actively. I also made sure that my external monitor refresh rates are 60Hz. Right now, it is not an issue and I can totally work from my main laptop screen, but it would be great to know if there is a fix for this. Maybe my laptop is not set up properly, it could be also an issue on my end.

Thank you,


I wanted to update you on my issue.

I did re-install clean Windows without the manufacturer’s add ons and that fixed the TouchDesigner freeze issue. It must have been the bloatware and by stripping PC to just Windows has fixed it. I hope this is useful for people who will be experiencing similar issues.

Thank you,

Thanks for the feedback, appreciated!

FYI I had same problem today when trying to “Open as Separate Window” from Window COMP… uninstalled Alienware Command Center and problem solved. Thanks everyone for the detective work!
