Hello,
When going into perform mode, TouchDesigner would become unresponsive or crash (Windows dialog “the program has stopped working”).
Crash:
It appeared on a workstation running 099.2017.16360, with a P5000 and mosaic enabled at a resolution of 11520 by 2160.
When Windows UI scaling is ON at a value that is over 100%, and that the Window COMP is set to DPI scaling = Use DPI scale and Opening size is set to Automatic from COMP/TOP.
Turning off DPI scale, setting it to Native and setting Opening size to Fill location solved the issue.
Unresponsive:
While I was not able to fully reproduce on another computer (running on a 1080), a similar behavior was being observed: TD was not crashing but the perform mode would not start and TD would become unresponsive until pressing on ESC. Turning off DPI scale, setting it to Native and setting Opening size to Fill location solved the issue.
It is not a big deal as my fix allowed me to get the output that I wanted. But maybe it is something that needs to be investigated further or that Derivative will be able to explain.
Regards,
Michel
