Output window freezes!

On Ubuntu 16.04, after building, and using this command below the output window appears and freezes...

BTW runninag as sudo since it gives OpenCL error: CL_OUT_OF_RESOURCES error if not.

Thank you for raising this issue, it is not one that I have come across before.
Is the bug repeatable or not?
Passing -a STEREO_SGBM as the algorithm makes the program use the OpenCV stereosgbm functions. This version does not have thread control or an explicit opencl implementation (stereosgbm may still use the GPU, through the TAPI, depending on how you have installed OpenCV).

I am working on an improved OpenCL implementation of the CVF at the moment, to solve the CL_OUT_OF_RESOURCES error and improve the execution time.
You shouldn't need to run with sudo. This may be just be masking the same problem and causing the program to crash. By using sudo you are just giving it permission to allocate memory where it shouldn't.
However, I can say for certain whetehr this is the source of the bug,
In the meantime, you can hard code the construction of sm to only use the pthread functions by passing 0 to the gotOpenCLDev field: StereoMatch *sm = new StereoMatch(argc, argv, 0);
This will stop the OpenCL compiler and OpenCL functions from being run.

Thanks for replying.
No difference without sudo. I reinstalled ubuntu (for another reason) and same error came up no CL_OUT_OF_RESOURCES this time, however:

1-Passing -a STEREO_SGBM gave the same error. (without sudo)
2-Passing -a STEREO_GIF gave the same things plus the ones pasted below: (without sudo)

HCI: Error threshold set to 4.
